Former Tottenham boss Tim Sherwood says Louis van Gaal's move to Manchester United will be no easy trip.
Sherwood, writing in the Independent, said: "The Premier League is an all-consuming competition to manage in. To my mind it is the most competitive league in the world and for all Van Gaal's experience, and all his success, he has never been there before.
"There is no time off in December and January as he has been used to in the Netherlands, Spain and Germany. There will be little time to acclimatise and get to know his squad. He cannot afford to miss one day of pre-season.
"As for the Premier League itself, it is unpredictable, even for a manager as experienced as Van Gaal. An understatement, but it is not an easy league to win. Every manager needs a pre-season to get to know his squad, and learn its strengths and weaknesses. So there will be no respite for Van Gaal as he goes from an exhausting World Cup finals straight into the build-up to the Premier League season."
