Martinez: Kid 'n' play for Caldwell

Caldwell did not have the best of matches during the weekend defeat to Bolton as Wigan lost 4-0 at the Reebok Stadium. And Martinez admits that January signing Caldwell's struggles have been down to him becoming a father. "He has been very solid for us and has a great partnership with Titus Bramble, but we are all human beings," said Martinez. "He is a father and has a newborn baby, sometimes that can affect you. "But he needs to play his football and get rid of that feeling from the weekend and the difference he is facing in his life. "Gary has got a nanny in and he is also sleeping in the spare room. I think there is also a mental side of becoming a dad and the extra responsibility. The structure of your family routine changes. "But he is a captain, he is a leader. He is going to get all of the help that we can give him. We just looked a bit drained at the weekend. Playing four games in 13 days is huge - sometimes you get situations like that."
