Shrewsbury Town defender Ro-Shaun Williams hopes to give Manchester United fans a boost by shocking Liverpool in the FA Cup tomorrow.

Williams left United last summer for Shrewsbury.

He told The Sun: “Marcus (Rashford) has watched us when he has had free time. He's been to our place and came to watch us at Barnsley last season as well.

“I've not spoken to him for a couple of weeks because he's a bit down with his back injury at the moment.

“But I know he'll be willing me on against Liverpool — not just because we're friends but also proud United fans have that rivalry with Liverpool."

On leaving United, he added: “It was my decision, no one else's. I had six months on my contract and spoke to Nicky Butt, head of first-team development.

“I told him, 'I believe I've enough talent to get to where I want but it's unrealistic to think I'm going to break into the United team having just turned 20.'

“It gets to the point where you think, 'I want to be a footballer, I want to play at the highest level I can and there's no point wasting my time in the Under-23s.'"
