Kevin De Bruyne has warned that Manchester United could flip the switch and rediscover their best form in this weekend’s derby against Manchester City.

United head into Saturday’s clash at Old Trafford ahead of their rivals in the Premier League but under the greater pressure having been eliminated from the Champions League in midweek.

United have been inconsistent throughout the campaign so far but, when questions have been asked after disappointing results, they have typically responded with a positive performance.

Opposite number Pep Guardiola feels that is unfair but something that goes with the territory.

“For me he’s an exceptional manager,” said the Spaniard. “I cannot say much because I am not there in the locker room but (it is because of) how he handled the team and how he represents United all around the world.

“I know, Ole knows, everyone knows it depends on results but I have a high opinion about his work at United.”

United have come from behind to win their last two Premier League matches.

City boss Guardiola said: “I know they came back against West Ham, against Southampton and almost against Leipzig. Against a big club you have to play for more than 90 minutes.”
