Everton are determined to keep Stones and will fight Chelsea's interest.

But behind the scenes, they are making contingency plans in case Stones departs.

And Colombia star Zapata is understood to be on Martinez's list of potential replacements.

Zapata, 28, was used sparingly by Milan last season - making just 13 appearances - and could be available at the right price.

Crystal Palace are keeping tabs on PSV Eindhoven goalkeeper Jeroen Zoet.

Having already signed goalkeeper Alex McCarthy from QPR this summer, Alan Pardew is eyeing another shot-stopper.

Pardew is a long term admirer of Zoet, 24, and was interested in the shot-stopper during his time at Newcastle.

Palace watched Zoet in PSV's Dutch Super Cup win over Groningen earlier this month and will continue to watch the keeper.

With long-time Palace No 1 Julian Speroni turning 37 next May, Pardew is on the look out for a keeper.

It remains to be seen whether a move for Zoet arrives in this window, but the keeper is certainly on the club's transfer radar.

The Canaries have a strong interest in Gayle and have been alerted to the fact he wants to stay in the top-flight.

Palace want Gayle to move to Ashton Gate; with City offering a remarkable deal to secure his signature.

Steve Cotterill's side are offering a fee worth up to £8million - and are willing to remove the sell-on clause owed to them from Yannick Bolaise's next move.
