Shkodran Mustafi could be set for a long spell on the sidelines after suffering an ankle injury during Arsenal's 2-1 FA Cup win at ​Bournemouth forcing the club into making an urgent defensive signing in January.


The German defender landed awkwardly on his ankle after a collision with Gunners goalkeeper Emiliano Martinez.


"I hope I'm wrong but when a central defender is taken off on a stretcher it is not usually good," ​Arteta said post-match. "We will find out more in the next days and we will assess it."



The Gunners already have problems in defence with Calum Chambers, Kieran Tierney, and Sead Kolasinac all out injured. Brazil defender David Luiz was also absent from their win on the south coast through suspension but will be available for their trip to ​Burnley in the ​Premier League on Sunday.


Mustafi, 27, has started Arsenal's past three matches. He was replaced by Rob Holding in an area of the pitch that Arteta has already determined needs reinforcement. Arsenal have been in talks over a £10million deal for 26-year-old Flamengo defender Pablo Mari but the move has currently stalled.


​The Spanish defender travelled from Brazil to London with Arsenal’s technical director Edu on Saturday but was unable to finalise his move over the weekend. The Gunners reportedly changed the terms of the transfer as they are unable to afford Mari’s £7.5m transfer fee up front and wanted a loan deal instead.


With just four days left until the close of the January transfer window, Arteta will be looking to move fast if the Gunners are to bring a replacement on board.
