West Ham United ace Declan Rice joining Manchester United this summer would be a mistake.

That is according to pundit Ally McCoist.

The Hammers captain is likely to leave the club when the season concludes, as he wants to play Champions League football.

Rice, however, will cost any club interested in his services at least £100 million.

“I'd be really concerned about going to Manchester United at this moment in time, I've got to be honest," McCoist told talkSPORT.

“I think they've done really, really well. If they could win the FA Cup which they'll be second favourites to do and finish in the top four I think it's a more than acceptable season. I think it's a really good season.

“However, the last couple of games have just kind of set alarm bells ringing in my head looking at them. I think they're probably further away than I initially thought. So I'm not sure about going there."
