The Catalan giants failed to win La Liga or the Champions League, losing out to Atletico Madrid in both, and as a result they are undergoing a transformation this summer. Manager Gerardo Martino has been replaced by former Barca star Luis Enrique, whilst experienced faces such as Victor Valdes, Carles Puyol and Xavi Hernandez will all be elsewhere by the start of the new season.
A number of players have reportedly been put up for sale, and the first of those – Cesc Fabregas – has already secured a move from the Camp Nou to Chelsea, and he could've been joined at Stamford Bridge by another surplus player, and another former Arsenal midfielder in Song.
The Cameroon international has found it hard to break into the Barcelona side since his 2012 move from Arsenal, where he was a key player under Arsene Wenger. With Sergio Busquets the undoubted first choice in defensive midfield, Song has been reduced to a bit-part role – leading to rumours that he would be sold to raise funds this summer.
That led to reported interest from Chelsea as well, with Jose Mourinho looking to revamp his central midfield options amidst interest in John Obi Mikel and Ramires from Inter Milan and Real Madrid respectively, whilst Frank Lampard has moved on at the end of his contract. Whilst Fabregas replaces the goalscoring nature of Lampard, Mourinho could well look to add another physical presence if Mikel or Ramires do leave – which would put Song in the frame.
However, the 26-year-old could have seriously damaged his chances of a move to a top club this summer after an unbelievable act of petulance in Cameroon's World Cup match against Croatia. Already trailing 1-0, Cameroon needed their experienced players to keep their heads and get themselves back in the game. Yet as half time drew ever closer, Song inexplicably elbowed Croatian striker Mario Mandzukic in the back, unsurprisingly resulting in a straight red card.
Mourinho will have no doubt been watching on as Song put his team in a more difficult position – something which will surely have put him off a potential move. The Blues will need steady players who can keep their cool in midfield, and having witnessed Song's temperament in Brazil, Mourinho could end Barcelona's hopes of selling the midfielder.
