Koeman says Guardiola might have found Premier League tougher than he expected

"Maybe, yes," Koeman replied when asked whether Guardiola had found the Premier League tougher than he expected.

"I think that, to see what happens in the Premier League, you need to be part of that;" the Dutch coach said. 

"Then you realise how difficult it is.

"Maybe the way he [Guardiola] likes to play, against the physical intensity of the Premier League, is more difficult."
