Cesc Fabregas will not face Celtic on Wednesday night.

The Arsenal captain picked up a hamstring strain against Portsmouth on Saturday and was withdrawn at half-time. Fabregas underwent a scan on the injured muscle on Tuesday morning.

Speaking at his pre-match press conference, Arsène Wenger described the scan results as "reassuring" but confirmed he will miss Wednesday night's clash.

"From last Saturday we lost Cesc Fabregas who did not train today" the manager said.

"His scan was quite reassuring as he has no muscular strain but it will take a few days to settle down.

"There's a chance he'll be fit for Old Trafford."
