NOTTINGHAM Forest manager Steve Cotterill has admitted he has taken a close look at Ipswich Town’s diamond midfield formation as the two sides prepare to meet tomorrow.

But it comes as his opposite number, Town boss Paul Jewell, is considering changes while leading scorer Michael Chopra admits teams have “started to work us out more”.

Despite going into the match off the back of three straight defeats, Town remain dangerous rivals, warned Cotterill who took up the City Ground hotseat last month.

He said: “Ipswich are a good side with some talented players and a very experienced manager so we know what we are up against.

“They are typical of the kind of side you meet in the Championship. On their day they are capable of beating anyone but that’s what you get in what I believe to be one of the toughest leagues in the world.

“We can’t under-estimate them, that’s for sure, and we have done some work on the training ground on how they play. They operate with a diamond system and we’ve taken a good look at that.

“But the important thing is that we play to our strengths and if we do that I’m hopeful we can get the right result.”

The Ipswich manager has revealed he is considering changes with Lee Martin and Josh Carson chomping at the bit to start and give the side some much-needed width.

And Chopra said: “I think teams have just started to work us out a little bit more, someone sitting on Jimmy (Bullard), someone sitting on Grant (Leadbitter), and it’s just stopped us getting the ball through the midfield.

“We’ve just got to believe in ourselves, because we’ve got some good players at a good football club here. The lads have been good in training, it’s been hard work but it’s also been enjoyable.”
