Leeds United will look to sign an experienced back up goalkeeper if Kiko Casilla leaves the club, according to Danny Mills.

Speaking exclusively to Football Insider, the former Whites and England defender pointed to the examples of Nigel Martyn and Rob Green of older keepers joining clubs to be the understudy.

Phil Hay of the Athletic reported on a recent podcast that he “understands” the Yorkshire giants will look to try and move on Casilla.

The one-time Spain international was omitted from Marcelo Bielsa’s matchday squad on Monday night against West Ham.

Asked whether a replacement will be needed for Casilla if he departs, Mills told Football Insider correspondent Connor Whitley: “Yes, definitely.

“I’ve looked at it in the past and goalkeepers that go in at certain situations. Nigel Martyn did it at Everton and went in as back up and never expected to play. Obviously, he’s an outstanding goalkeeper and put pressure on the number one at the time and ended up taking the jersey.

“Rob Green did it when he came into Leeds, then Huddersfield and then onto Chelsea.

“Maybe a keeper coming towards the end of his career like Martyn who accepts he isn’t going to play week in, week out but is still a good professional, is going to train hard, push the number one goalkeeper to improve them day in, day out.

“You get that good balance so if you do need somebody to step in you’ve got good experience and it’s not a problem.

“And it’s good for a young goalkeeper to learn their trade that way.”
