Colin Calderwood has challenged his Nottingham Forest side to up the ante in their remaining pre-season games.Goals from Arron Davies, Lewis McGugan and Nathan Tyson helped Forest battle from behind to beat Burton 3-1 on Tuesday night.

The Forest boss is now keen to see some improvement from his squad as they build up to the new campaign, with matches to come against Telford, Everton, Sunderland and Notts County.

"I would like us to have played better [against Burton] if I'm honest," he said.

"I didn't think we had any continuity in our play for long enough, but it was the first time that group had played together as a team as we're mixing the players up to maximise the fitness element of pre-season.

"But there will have to be a lot of improvement all round to go anywhere near pleasing any of the coaching staff."
