Fabregas, 27, completed his controversial switch to Stamford Bridge on Thursday after realising he had no future with the Catalan giants, and Blues boss Jose Mourinho has seemingly landed the long-term midfield partner for Serbian Nemanja Matic, with the former Benfica man expected to sit in front of the back four and allow Fabregas to go forward and support the attack.
Yet with Frank Lampard leaving the club as well as Ramires and John Obi Mikel both linked with moves away from West London, Mourinho could well be looking to bring in at least one more central midfielder – and speculation this morning suggests that Fabregas could be joined by a familiar face.
Midfielder Alex Song is currently at the World Cup with Cameroon, but was a team mate of Fabregas with both Barcelona and Chelsea's London rivals Arsenal. The 26-year-old impressed with the Gunners during the 2011/12 season, but moved on from the Emirates Stadium at the end of the season for Barcelona.
Yet with the likes of Sergio Busquets, Xavi and Andres Iniesta starring for Barca, Song has found first-team football hard to come by, and with a number of teams lining up to sign him, it appears his future lies away from the Camp Nou – and a move will surely take place this summer.
Manchester United were strongly linked whilst David Moyes was manager of the Red Devils but his departure has seemingly ended all possibility of that move, whilst Arsenal were reportedly interested in bringing him back to North London - yet now Chelsea are the favourites to land him.
That was also the case with Fabregas, and Gunners fans were upset when his switch to Chelsea was confirmed. The relationship between the two clubs is already frayed after repeated tension between Mourinho and Arsenal boss Arsene Wenger – and signing two former Arsenal midfielders would surely make things even worse.
That could be just what Mourinho wants, but on the pitch, Song offers physicality that Chelsea will need if Mikel and Ramires do leave the club this summer. It could be seen as a signing geared towards irritating Arsenal even more, but the Cameroonian could be sensible addition for the Blues – at the right price.
