Arsene Wenger has confirmed that new signing Gabriel is facing up to three weeks on the sidelines after sustaining a hamstring injury against Queens Park Rangers.
The Brazilian centre-back was replaced by Laurent Koscielny after just 37 minutes at Loftus Road and now looks set to miss the Gunners next four games against Manchester United in the FA Cup, West Ham and Newcastle in the league and the second leg of the Champions League tie with Monaco.
“Gabriel has a hamstring injury and he will be out for two to three weeks,” said Wenger.
The injury means it’s almost certain Per Mertesacker will partner Laurent Koscielny at Old Trafford on Monday. Nacho Monreal, who missed the Gunners 2-1 win on Wednesday with a back strain, should be able to provide further cover for the rest of the month, he’ll have a fitness test today.
