Town manager Joe Royle says he was annoyed by comments made by on-loan keeper Andy Marshall after his Millwall side defeated Town 3-1 at Portman Road on Saturday.
Marshall said he felt the Lions were mentally a stronger side than the Blues. Royle says the stopper should not have made his comments: "I was disappointed with Andy. He should know better than to think that after working with these players.
"I appreciate things are rocking at Millwall, and I'm genuinely pleased for him that he is doing well there, but I felt his comments were wrong."
