Brown: 'Celtic can only improve'

Gerrard has reportedly identified fitness as one area where Rangers can improve, but Brown has no such worries. 

"We score a lot more goals in the last 15/20 minutes of games because we have a lot more of the ball and we create more chances," Brown said.

"We work harder than every other team that we play against and that is down to what we do out there on the training pitch with the fitness coaches and the manager. The lads want to get fitter than what they were last season.

"We dropped a lot of sloppy points, especially at home in front of the fans. We have a new pitch and there are no excuses. The pitch will be fantastic all season and we can play proper football on it."
