Chelsea are often criticised for letting players go on to enjoy success at other clubs when really they may be of use at Stamford Bridge.
Romelu Lukaku, who is on loan at Everton, or former Blue Daniel Sturridge have been hitting the net regularly, while on-loan Victor Moses may well pick up a Premier League winner's medal with Liverpool this season.
While the Blues struggled to an uninspiring 1-0 win over Swansea City, former Stamford Bridge man Kevin De Bruyne put in a perfect-10 performance for Wolfsburg, as he became WhoScored.com's player of the week.
The Belgium international registered two assists from an incredible eight key passes as he ran riot in the Nurnberg defence, also completing five successful dribbles and attempting three shots of his own. He will be playing at the World Cup finals in Brazil and could show Chelsea fans what they are missing on the biggest stage of all.
He is joined on the opposite flank by team-mate Ivan Perisic, who had De Bruyne to thank for the first of his goals as he bagged twice in the 4-1 win. The Croat scored with both of his efforts on target and was also integral without the ball, making a combined total of seven tackles and interceptions.
The midfield is completed by fellow Bundesliga star Lars Stindl and Serie A's Alberto Aquilani.
The Italian was the second-best performer in Europe's top-five leagues, registering an impressive 9.9 rating as he netted twice in Fiorentina's dramatic 5-3 win at Verona. He completed 95 percent of his passes in the win, which keeps La Viola in fourth place in the table.
Stindl scored a rare goal as he played a more advanced role in behind the striker, as Hannover picked up a vital win over Hamburg. Stindl, often a defensive midfielder and barely ever a goal threat, exploded in attack, attempting 10 shots. On only nine occasions has a player had more shots in a game this season, four of which were Cristiano Ronaldo.
The strike force is made up of Rodrigo Palacio and Alberto Paloschi, who directly contributed to a total of seven goals between them this weekend.
Palacio scored twice and set up another in Inter's 4-0 win over Sampdoria, which was overshadowed by the off-the-field antics involving Mauro Icardi and Maxi Lopez, as The Metro reported.
Paloschi bagged a hat-trick and set up the other of Chievo's four goals as they overcame Livorno in a highly efficient win. They had only 41 percent possession, with Paloschi doing such vast damage despite only touching the ball 35 times.
Hoffenheim have not been renowned for their defensive record this season, and have the worst "goals against'" column in the Bundesliga. But they kept their first clean sheet of the season on Sunday in a 2-0 win over Augsburg despite conceding 23 shots.
Goalkeeper Jens Grahl and centre-back Jannik Vestergaard were key and both make it into the team of the week with respective ratings of 9.3 and 9.4. Grahl made eight saves and successfully claimed five crosses, while Vestergaard made five tackles, five interceptions and six clearances to go with his goal.
Cardiff's Juan Cala scored a wonder goal that gave the Bluebirds a lifeline in their relegation battle as he exhibited the skills of a winger, skipping past the challenge of Steven Davis before unleashing an unstoppable drive across Paulo Gazzaniga and into the corner. The Spaniard also provided a match-high nine tackles and interceptions as well as 10 clearances and a last-ditch tackle.
The full-backs in the team of the week are Mainz's Zdenek Pospech who picked up an assist and made six successful dribbles at the weekend, and Freiburg's Christian Gunter, who completed one more dribble and delivered five key passes from left-back, whilst also making five tackles.
