Chelsea boss Guus Hiddink has identified a prime weakness at Manchester United.
Hiddink admits they will target the pace of fellow Dutchman Danny Blind.
“This is not a criticism," he said. “I know this player. Of course he's not the fastest player but he's technically very keen. He has to adapt to the pace of the games.
“There are not moments of a pause in games and players have to get used to that and know how to cope with that.
“Blind knows that he's not the fastest player but he copes with that, because when he's not the fastest he can start a bit earlier."
