Manchester United boss Ole Gunnar Solskjaer worries Alexis Sanchez may have damaged his ligaments in Saturday’s clash with Southampton, which would rule him out of the clash with Arsenal.

Sanchez was forced off early in the second half against Southampton, with Diogo Dalot replacing him. Speaking after the match, Solskjaer said they don’t know how bad the injury is yet, but there’s some concern it may be ligament damage.

“We don’t know yet. He got a knock on his knee,” Solskjaer said. “It might be his ligaments. We’ll do the scan tomorrow. Hopefully, it won’t be too bad but we won’t know until we’ve done the scans. Of course, we’ll have to wait until then.”

If the Chilean forward has damaged his ligaments, or even suffered a more minor injury, it would keep him out of Manchester United’s trip to the Emirates Stadium next weekend. It would also mean he’d miss out on his team’s attempt to overturn a 2-0 deficit against PSG in the Champions League in midweek.

That’s probably a good thing for Arsenal. Sanchez has been one of the biggest flops of recent years with United, but the one game this season he did turn up for was his trip to the Emirates Stadium.

Henrikh Mkhitaryan may have contributed to more league goals in his last three matches than the ex-Arsenal star has all season, but you just know Sanchez would suddenly recapture his old form for 90 minutes against the Gunners. We’ll see what the results of his scan tell us.
