Serie A side AS Roma are losing patience with Manchester United over the transfer of Chris Smalling.

The Rome based side are ready to switch to a plan B after both parties have failed to agree on the tranfer fee.

Roma are in the market for a new centre-half with immediate alacrity after United decided to stall the Smalling deal and the Serie A starts soon.

United sent Smalling out on loan last term and he had successful loan spell in Rome.

The English international has decided to leave Manchester United this summer after he appears to not be in Solskjaer’s plan.

A deal for the 31-year-old could be off the cards with Roma running out of time.

£20million is what Manchester United are willing to accept for the central defender and Roma are not ready to cough out such amount for Chris.

With Serie A billed to commence this weekend, Roma want a new centre-half urgently.

Smalling didn’t take part in United’s photoshoots for TV on Monday as he reiterated that he’s not going to stay at Old Trafford.

Smalling also trains separately away from Manchester United first-team squad.

Smalling had a successful loan at Roma last season and is determined to leave Old Trafford.

He was also absent from training on Tuesday and Wednesday last week as he discussed his future and with Ole Gunnar Solskjaer and since there’s no positive response coming from the gaffer he has made up his mind to leave Old Trafford.
