Only a few days ago, Arsene Wenger talked about his side's inability to defend set pieces, something that came to haunt him at the end of the season. Arsenal finished last season trophyless, despite being in contention for four different trophies, including the Champions League and Premier League, in January.
The way everything collapsed was nothing short of spectacular. Most of it was attributed to the inept defending of Laurent Koscielny and Sebastien Squillaci. Hence, Wenger definitely seems to have made signing a defender as the top priority. A few weeks ago, Arsenal were linked with a move for Phil Jones and Birmingham's Scott Dann, but both these did not materialise.
Now, Arsenal have made an official bid for Everton's Phil Jagielka, with the offer reported to be around £10 million. Incidentally, this is not the first time Arsenal have shown their interest in the England international. The £10 million offer may not be enough to persuade Everton to sell the player, especially given the going rate for a domestic player.
Arsenal may well return with an improved bid, which could be crucial in getting a player seen as the missing link. William Gallas could have been a great partner for Arsenal, but he left shortly after Thomas Vermaelen's arrival.
Since then, Vermaelen has not had a proper partner fit enough to be paired alongside him. Jagielka may just be that player, and it is only a huge bonus that Arsenal will be getting a wealth of experience as well.
Ronald Koeman has created history by taking over the managerial vacancy at Feyenoord. Koeman has now managed all three big clubs in Eredivisie. Even though the last couple of years has not been particularly good for Koeman, he has enjoyed great success managing in the Dutch league. Best known for his time at Ajax, Koeman won the title on numerous occasions during his four-year stint at the club. Success soon followed in the form of Eredivisie titles at PSV.
Since then, though, it has been nothing but downhill for the former Dutch international. He made his major move to La Liga in 2007 to manage Valencia, but it turned out to be one of the greatest managerial disasters. He left the club after only six months and things have never really recovered for him.
Feyenoord is going to be a great test for both club and manager. The club are struggling financially with saddles of debt attempting to strangle the club. Koeman will know the club and its roots extremely well, having played for the 2002 UEFA Cup (today's equivalent of the Europa League) winners from 1995 to 1997.
They finished last season in the 10th place, which is a clear indication of the bad times they are in.
In a way, Koeman is the perfect man for the job, as he has a lot to prove. Should he fail yet again, his managerial career will undoubtedly be in jeopardy.
