Goalkeeper Lee Nicholls wants to challenge David Martin for the number one shirt at Stadium MK after signing from Wigan on Wednesday.
The 23-year-old stopper has spent time on loan at Northampton, Accrington and Bristol Rovers during his career, but found first team opportunities at the DW Stadium hard to come by.
Having signed a two-year deal for Karl Robinson’s side, Nicholls has his sights set on playing regularly for his new club.
“I wasn’t really getting a chance at Wigan,” he said. “I want to play games, so all I can do is work hard and really push for playing time.
“I’m over the moon. There were a couple of clubs interested but I feel MK Dons are going in the right direction – it was a no brainer for me.
“I like to be dominant and when I play football, I like to be aggressive - my stature and my size really helps with that.”
Manager Robinson said: “I worked with him at Liverpool when he was a central-midfield player and he came back two years later as a goalkeeper.
“He’s someone who I’m really excited about. He’s six-foot-five and his feet are outstanding. (Andy) King used to tell me every Saturday when he was manager of Northampton that he was brilliant. I also spoke to Tim Flowers as well and he raved about him.
“Every player needs to be pushed and he’ll definitely add to the competition in the goalkeeper position.”
