Danny Mills has claimed that Kiko Casilla could look to leave Leeds United this summer.

Speaking exclusively to Football Insider, the former Elland Road defender suggested that the veteran Spaniard “might find it difficult” to play understudy to Illan Meslier, and may seek first team opportunities elsewhere.

As revealed by Football Insider, the former Real Madrid stopper has already been told that he will be Marcelo Bielsa’s number two going into the new Premier League season.

The Whites made Meslier’s loan move from FC Lorient permanent last month after an impressive debut season in England.

And Mills is unsure whether Casilla will be willing to deputise for the young Frenchman.

Speaking to Football Insider, he said: “He’s been deputy before, but I guess being deputy at Real Madrid is a little bit different to being deputy at Leeds United, when you’re winning Champions League and so forth.

“He might find it difficult. He might want to go and be number one somewhere, and good luck to him.

“People might say that Meslier is very young, but Dean Henderson and Jordan Pickford were young when they got their chance. Goalkeepers aren’t under the same physical pressures that they once were. Teams aren’t putting balls into the box that often. It’s more about shot stopping and distribution.

“If Meslier can do that well, I’m pretty sure that Bielsa will have faith in him. But you do need a decent, senior back-up option. Whether that’s Kiko Casilla, we’ll see. Leeds might have to bring someone else in.”

Casilla started last season as Bielsa’s number one between the sticks but was displaced in the latter stages of the campaign while serving a lengthy ban for racially abusing Charlton Athletic forward Jonathan Leko.

The 20-year-old Meslier showed good form during his absence, keeping seven clean sheets in 10 appearances and conceding just four goals.

In other news, Leeds United have submitted a formal bid for another forward as they plot latest signing.
