Arsenal defender Nacho Monreal facing late fitness test

Arsenal manager Arsene Wenger has revealed that Nacho Monreal will undergo a late fitness test ahead of tonight's FA Cup quarter-final away to Manchester United.

The defender was forced to miss last week's 2-1 win over Queens Park Rangers in the Premier League with a back problem.

However, the Spaniard could return to the squad for this evening's highly-anticipated clash at Old Trafford.

"We will of course lose Gabriel [Paulista] in the squad and Nacho Monreal might come back," Wenger told the club's official website. "He will have a test today. Everybody else should be available - the same squad that played against Queens Park Rangers."

Arsenal head to Old Trafford having won five of their last six games in all competitions.
