Birmingham boss Lee Clark believes new signing David Lucas can compete with Jack Butland and Colin Doyle for the No.1 spot at St Andrew's.
Birmingham have confirmed that Lucas has signed a one-year contract at the Championship club, as revealed by Sky Sports earlier on Tuesday.
The 34-year-old was released by Rochdale at the end of last season and will provide Clark with an experienced goalkeeping option.
But the Blues boss insists that the signing forms part of his intention to have three quality keepers at the club and does not pave the way for a sale of youngster Butland.
"I'm delighted to welcome David to the club and he will now compete with Jack and Colin for the No.1 spot," Clark told the club's official website.
"It's very important for us to always have three senior goalkeepers to call upon because, for example, we could find ourselves without Jack Butland for the Capital One Cup tie against Barnet (on August 14) due to international duty."
Butland has been selected in Stuart Pearce's Team GB Olympic squad, the final of which takes place on August 11, and could feature in England's squad to face Italy on August 15.
