Sheffield United boss Chris Wilder is adamant Rhian Brewster will prove his ability.

The highly rated 20-year-old moved to Bramall Lane from Liverpool last summer in a deal worth £23.5million, agreeing a five-year deal.

Brewster's wait for a first goal was extended to 20 appearances as United beat Bristol City 1-0 in the FA Cup fifth round on Wednesday night.

“I have said it all along, Rhian is a natural goalscorer whatever level, whether for Liverpool, England or on loan at Swansea," said Wilder.

“Getting over the line and getting that first goal will be key for him and the longer it goes on the more difficult it becomes. He could do with one of those that drops to him, but he gets in good positions and he will be fine.

“It's a cut-throat business that we are in and a business that everyone makes instant assumptions, opinions and deliveries on what people are about.

“It's a tough period for him, but it won't hurt him. He's a tough cookie, an east London boy. He won't be enjoying this because he wants to score goals and play well and win. He'll come through it.

“It's a tough learning curve. I feel for him because I know how much he wants to do well and how much he wanted to come and join us.

“He has not shied away from that, he has not sulked, he has got on with it. He has had to play against some tremendous opposition but he will learn from this experience and he's going to be a good player for us I am sure."
