Arsenal midfielder Santi Cazorla expects next season's title race to be among a crowded field.
David Moyes has taken over at Manchester United following Sir Alex Ferguson's retirement, while Jose Mourinho has returned to Chelsea and Manuel Pellegrini is now in charge at Manchester City.
"The most radical change is at Manchester United because Ferguson has been there for so long," the Spaniard told the official Arsenal Magazine.
"It will be a little difficult at the start for a new manager but I don't think it influences too much in terms of being an advantage for other teams. There are great managers at those clubs and I'm sure [the title race] will be just as difficult."
