The Manchester United football club's goalkeeping coach admits it'll be hard to replace Edwin van der Sar.
The veteran Dutch keeper's announced he will retire at the end of the current season after joining the Red Devils in 2005 from Fulham.
Van der Sar has made almost 250 appearances for United and has won three Premier League titles and one Champions League... and Eric Steel says he'll be a tough act to follow, comparing him to former United star Peter Schmeichel, the Great Dane.
