Philippe Clement has vowed to fight to keep Jack Butland at Rangers amid persistent speculation that a transfer move is in the offing.

Reports suggest new Birmingham City manager Wayne Rooney is set to table a bid for his former England teammate in January.

It's understood there is interest in the player's services from clubs in England after a stunning start to his Ibrox career.

When he was asked if he would reject any approaches for the player, Clement said: "Yeah, for sure, I am really happy with Jack. Not only on the pitch with his performances, but also outside the pitch and in the dressing room. In the way he works, the way he acts and his personality.

"Jack is going to be one of the key figures to build a team around for the next couple of years, yes. It's clear, when you have a s*** goalkeeper, you can't have success! That's very clear. That is the same for every manager.

"Of course you have to keep clean sheets. That's not down to the goalkeeper or defence, it's the whole team working together. But to have real success and to win trophies, you need to have somebody who gives the team a life in the difficult moments. Jack did that in the first half in Prague and he will do it again in the future.

"He will also make mistakes. That is part of being a goalkeeper. But what I like most about him is his personality. He is a winner. Jack has a strong mindset and I like to have these characters in my dressing-room.”
