Manchester United Treble winner Teddy Sheringham says manager Ole Gunnar Solskjaer needs a trophy to keep his job.

United are left fighting on the three fronts of the Premier League, FA Cup and Champions League after they were knocked out of the Carabao Cup by West Ham last week.

"Without a doubt there is pressure on him this year to win something. If he doesn't win something, he knows the writing is on the wall," Sheringham told the Daily Mail.

"They have made the big signings in Varane and Sancho. That would be enough but then Ronaldo becomes available, United acquire him and they need to see results now.

"Ole is still a young manager and he is gaining experience while on the job. At the top level he only knows United and that is a hard job to leave. I think he is progressing but he needs to take it to the next level.

"I think everybody is willing him to do well, they want him to do well because he is a Manchester United legend.

"That gives him some scope but you have to emphasise, he needs to win something. It's not rocket science."
