Marcus Rashford is unlikely to be fit for Manchester United's clash with Liverpool on Sunday, according to manager Ole Gunnar Solskjaer.

Rashford came off the bench and was involved in Juan Mata's winning goal just minutes later as United beat Wolves 1-0 in the FA Cup third-round replay.

The striker was forced off 10 minutes from time with an apparent back problem, however, with Solskjaer admitting the plan to use Rashford had "backfired".

Solskjaer later assured they would do everything possible to get Rashford fit for the trip to Anfield, but he is not convinced he will be ready.

"I can't tell you now," Solskjaer told reporters on Friday when asked whether Rashford would be available.

"We'll do some more checks and treatment with him today. I'm not going to hold my breath. But let's see.

"As I said with Harry [Maguire] a few weeks ago, of course we're going to give him the absolute amount of time to find out.

"We're going to do some more checks and treatment with him today. Yesterday, of course, was just a recovery day anyway and some treatment for him.

"I haven't seen him this morning, but I'm not going to hold my breath. I would probably think that he wouldn't be ready, but let's see. There's still 48 hours, more than that, so let's see."
