An injury to Kieran Gibbs will prompt Arsenal to dip into the transfer market for a new left-back, according to manager Arsene Wenger.
The England defender had to be substituted after just 30 minutes of the Gunners thrilling 2-2 draw with Liverpool on Wednesday night.
The Gunners boss confirmed Gibbs would be out of action for three weeks with a thigh strain and admitted he would probably have to search the transfer market for cover.
According to The Mirror, Wenger has lost faith in Brazil left-back Andre Santos and will try to find a replacement on the January transfer window deadline day.
“I’ll see what I can do,” he said when asked whether he would be looking for cover in that position.
“It is a thigh strain and that rules him out for the next three weeks.
“Of course it is a big blow because Gibbs was a big player for us going forward and in the game we want to play it is a shame he is out for three weeks.”
Santos’ form has been poor for some time and many fans at Emirates Stadium have been highly critical of him, including on Wednesday night.
Arsenal were forced to come back again after Liverpool had taken a 2-0 lead owing to some calamitous defending handed chances to Luis Suarez and Jordan Henderson to score.
Olivier Giroud and Theo Walcott scored in quick succession to level the game but the Gunners could not find the winner.
