Rooney is very important to Man Utd - van der Sar
The England forward continues to be linked with a summer exit at Old Trafford but former keeper van der Sar has urged the ex-Everton young gun to remain with the Premier League champions.
"It was maybe a lesser season and he didn't play the last couple of games but he's really important for United," Van der Sar told BBC Radio 5 Live's Sportsweek programme.
"English players tend to stay in England to play their football and rightly so because you have big clubs, the tradition and the stadiums are always full.
"With the change of manager and backroom staff it could be a big change for Manchester United but I don't think you'll find a better atmosphere at many other clubs."
