Boss Roy Keane says he wants new loan signing Asmir Begovic to fight Richard Wright for his place in the first team. The Bosnian international has joined the Blues on a three-month loan.
Keane told the club site: "With Shane Supple retiring, it left us a bit light. Although we brought Arran [Lee-Barrett] in, I've always liked three keepers in my squad to maintain the competition and Asmir comes here to push for a first team place.
"I spoke to the Portsmouth manager Paul Hart about him and a few other people and they have been very positive, but most importantly for me I spoke to the lad himself and he was very keen to come here and wants to play games, and that was a good plus for me."
Lee-Barrett, who is yet to make a first team appearance for the Blues, is on a short-term contract until January, while Bohemians keeper Brian Murphy is set to join Town on a Bosman at the end of the Irish season in November.
