Brendan Rodgers has suggested that Manchester United manager Louis van Gaal may be in for a surprise ahead of his first season in the Premier League.

Van Gaal has been given the task of turning United into challengers once again following a difficult campaign under the guidance of David Moyes, but Liverpool boss Rodgers believes that the test will be like no other the Dutchman has faced in his career.

"I think what he'll find is the competition in this league will be different from any other league that he's worked in," Rodgers told reporters. "In a lot of the other leagues there are one or two teams and those are the teams that are expected to win.

"This is a league where the top team plays the bottom team and on any given day you can lose. You don't get that a lot in the other leagues. I think the competition will probably take him by surprise, and that's from foreign managers I have spoken to over the years.

"I've worked closely with foreign players who have come in and that real physical competitive nature will be different from anywhere else he's worked before."

Van Gaal's side recorded a 3-1 victory over Liverpool in Miami in the early hours of Tuesday morning to end their tour of the USA on a high.
