Norwich City boss Chris Hughton admits they face a testing Christmas period.
Hughton knows if his side do not maintain their excellent work rate, the next three fixtures - away to West Brom and at home to Chelsea then Manchester City - may not bring much festive cheer.
"Every match is still tough for us and we have to be on top of our game to win," Hughton said.
"We know we have to be disciplined in every performance and everything has to be based on a real hard-working team ethic.
"At some stage we will not be able to continue this run because, for a team like us, it is impossible
"But at the moment, we are in good form and giving everything to get a result. If you can do that, then you always have a chance."
