Taking to Twitter, Romano said: "Chelsea are still considering Declan Rice as their main target.

"Chelsea are now working to sell players then will try again to sign him.

"West Ham insist they won’t sell Rice on next days and “he’s gonna stay”.

"Not easy deal - but still on."

GIVEMESPORT'S Phil Spencer says...

This is a deal that could rumble on until the very end of the transfer window.

It's no secret that Declan Rice is a long-term target for Chelsea, but the question mark remains over whether a deal can get done.

Valued at £44.55million by Transfermarkt, the West Ham star will not come cheap.

David Moyes' side are gearing up for a long, hard season and that will only be made worse if they lose their talisman.

That means that it will take a substantial offer to make the Hammers even consider cashing in.

Whether Chelsea see the value in splashing out a huge sum on the player remains to be seen, but if Frank Lampard sees him as the final piece of his jigsaw then they may have little choice but to splash out.
