Laurent Koscielny continued his rehabilitation on Tuesday with an appearance for our under-21s in a Checkatrade Trophy game at Portsmouth.
We lost 2-1 but Laurent completed 85 minutes and has come through the game without complications.
Laurent, who played 45 minutes for our under-23s at Derby last week, will not be involved against Manchester United tonight.
He will be assessed ahead of Saturday’s Premier League game against Huddersfield Town at Emirates Stadium.
