World Football: Best 2011 Summer Signings, Club by Club
Over the summer all the big teams made signings that have affected their present and their future.
Some of these signings have had a great impact on their teams fortunes so far this season and others are great long-term projects.
It does not necessarily matter what the player's age, cost or current talent level is, but it matters just how positive an impact they will have on the club.
When tomorrow comes, new signings will be made, but this list looks at some of the best summer signings on a club-by-club basis.
Click through the slides and enjoy...
Manchester City: Sergio Aguero
Sergio Aguero has scored 15 goals and added four assists in 24 games in all competitions. At the age of 23, he can lead the line for Manchester City for years to come.
He is part of the reason that City's offense has exploded this year
Manchester United: Phil Jones
David De Gea had some bad moments early on and Ashley Young has been solid, but Phil Jones was a really good buy for Manchester United.
At 19 years of age, he is the long-term future defender for this Manchester United team and he has already shown his potential on numerous occasions. He also has the versatility to play in the midfield.
He has chipped in with a goal and assist or two as well.
Tottenham: Emmanuel Adebayor
Scott Parker is good but his age will soon catch up with him. Spurs do have some good help in his position as Sandro will get better and Tom Huddlestone is missing through injury and both will be there long-term.
Emmanuel Adebayor has notched nine goals along with six assists in 15 games for Tottenham. He has been involved in 15 of Tottenham's 34 goals, almost half their output.
Adebayor may be a loan signing right now but he has been big for Spurs.
Chelsea: Juan Mata
Juan Mata has been a key creative force in Andre Villas-Boas's Chelsea squad. Mata has five goals and nine assists to his name while playing in all competitions for Chelsea.
He has been instrumental in helping to implement Villas-Boas's attacking philosophy in the Chelsea attack.
Liverpool: Jose Enrique
Liverpool has shuffled a variety of left-backs in and out of Anfield for the last few years and Jose Enrique may put a stop to that.
He has been a solid buy and decently priced buy for the Merseyside club and is part of one the best defenses in the league.
Arsenal: Mikel Arteta
Mikel Arteta has helped calm the Arsenal midfield just as Arsene Wenger would have hoped. Gervinho has scored some goals and added assists but that may not have been the case without the Spanish midfielder.
Arteta's presence has helped both Aaron Ramsey and Alex Song be more comfortable in their duties and he has formed a great partnership with them, thus allowing Arsenal to climb up the table as they did.
He will continue to have an influence on all even when Jack Wilshere returns and it is likely he could keep his starting spot when that happens.
Real Madrid: Nuri Sahin
Nuri Sahin's playing time has been hampered due to injury and the continued good form of Xabi Alonso. It is safe to say that the Turkish player will take over from Alonso when all is said and done.
He has the playmaking abilities and is capable enough defensively to do exactly the same job as Alonso for years to come in midfield. He may still get his chance to have a major impact on the team's fortunes but he will be just as good long-term.
Barcelona: Cesc Fabregas
Cesc Fabregas has been absolutely great for Barcelona so far. He fit right back into the squad and has scored 11 goals with five assists in all competitions. He has picked up a couple trophies as well, even scoring in the European Super Cup and the Club World Cup final.
Fabregas has given Barcelona a versatile attacking option and their best midfield scoring threat.
Inter Milan: Yuto Nagatomo
Yuto Nagatomo has added some youth to an aging Inter Milan defense. Nagatomo has appeared in 20 games in all competitions for the Nerazzurri and has two goals and three assists to his name.
He is a good long-term option for Inter at left-back.
Juventus: Andrea Pirlo
His statistics might not tell on the field with only three assists to his name but Andrea Pirlo has been a major piece for Juventus this season.
Players like Alessandro Matri have undoubtedly made a good impression as well but it is hard to see where this Juventus team would be without this throwback Pirlo. He was the teams best summer signing.
AC Milan: Zlatan Ibrahimovic
It was a close one between Zlatan Ibrahimovic and Kevin-Prince Boateng but Ibrahimovic wins out. Boateng has provided the midfield with and energy and drive that is much needed and has done a solid job from midfield.
Ibrahimovic has 16 goals and three assists to his name and remains the integral piece in the Milan attack.
Bayern Munich: Manuel Neuer
Bayern Munich has finally found its long-term replacement for Oliver Kahn. Manuel Neuer is one of the surest goalkeepers around and that is how has been for Bayern.
He has 16 clean sheets in all competitions and when he it comes down to it, he may be the difference between a win and a loss for Bayern in a close game.
Paris Saint-Germain: Javier Pastore
Javier Pastore is part of a whole new PSG team but he is probably the most important piece. PSG needed a playmaker to help pull together all the various pieces they had and of all the players available Pastore was a good choice.
The Argentinian is the youngest recruit and the one with the most potential. Players like Jeremy Menez and Kevin Gameiro have been major factors in the attack as well but this will be Pastore's team.
He has eight goals and three assists to his name in all competitions so far.
Lyon: Bakary Kone
Lyon have not made too many moves this summer but they did pick up a good player in Burkina Faso defender Bakary Kone.
Kone has played in 23 games for his new club and has scored three goals. He may be another young player that the team hones into a great player.
Marseille: Nicolas N'Koulou
Nicolas N'Koulou is another young African defender who could be a future star of Marseille or in Europe. He attracted interest from Arsenal at one point but right now he continues to play in Ligue 1.
N'Koulou has been a constant figure in the Marseille lineup, featuring in 22 games for his team.
This one may be a bit weird seeing as the player has yet to play for the club but he was bought in the summer so it counts.
Porto has a knack for picking up great young talent and selling them at a profit and it will be no different with Danilo. He has impressed with Santos this year and chose a good route to Europe. When he touches down in January he should be able to help his new team right away.
Ezequiel Garay is finding new life after Real Madrid and he has been good for the Benfica squad but Nolito has been great.
The young Spaniard decided not to stay on at Barcelona—probably a wise choice for his own playing benefits—and Benfica are certainly happy he did that. He has scored 10 goals and added two assist in all competitions for the Portuguese side.
Ajax: Kolbeinn Sigthórsson
Kolbeinn Sigthórsson could be one of the new players to make a big splash at Ajax. The young Icelandic forward is currently out with injury but has made a good impression with the games he has played thus far.
He has scored five goals and added one assist in eight games and may just be one for the future.
PSV: Georginio Wijnaldum
If we are looking at statistics alone Dries Mertens wins. He has 13 goals and nine assist to his name in the Eredivisie. Georginio Wijnaldum has seven goals and five assists to his name.
The potential that Georginio Wijnaldum has is really good. He is the younger of the two players and plays in a less advanced position yet he has been very, very productive for his squad. Mertens has been really good but Wijnaldum may have a better future.
