Barcelona's agent has put both Arsenal and Liverpool on red alert after confirming that his client is looking to leave the Nou Camp in the January window.
The defender has been deprived of first team chances under new boss Luis Enrique this season and has played just one game in La Liga. The arrival of a host of defenders over the summer seemed to put paid to his chances of establishing himself in the starting XI, and now it seems as though he's seeking a move.
Currently ahead of Montoya in the Barcelona pecking order is Dani Alves, and even if he leaves Brazilian Douglas will likely take his place. Agent Juan De Dios Carrasco said: "Martin Montoya wants to leave Barcelona.The coach decides who plays, but if Martin does not play he will leave.
"We do not want to argue about who is to blame, it is just important that Montoya wants to go already."
That is huge news for the likes of Arsenal and Liverpool who are said to be in the running for his signature. Both sides are in dire need of more options at the back having struggled badly in defence this term.
Arsenal shipped three goals in their defeat against Stoke which dropped them down to sixth in the Premier League table having won just six games this season. Injuries have also taken their toll as well with youngsters and squad players including Hector Bellerin and Nacho Monreal forced to step in.
Liverpool have hardly fared much better either and are even further back than Arsenal in ninth place. They spent big to bolster their squad in the summer but that move appears to have backfired and now they are struggling badly.
One of Liverpool boss Brendan Rodgers' biggest problems is at the back, where the likes of Dejan Lovren and Javi Manquillo has failed to settle. With Glen Johnson likely to leave Anfield in the summer, Montoya could be the perfect replacement.
