Van der Sar concerned over lack of firepower in Man Utd attack
Van der Sar admits they need to improve their scoring record next term.
"It is very good that we have the best defensive record," the Dutch veteran told the Manchester Evening News. "We had it last year as well. We had that great run of clean sheets last year. This year it has been a bit back and forth in defence.
"We've had midfielders in the back four at times; right-backs playing at left-back and goalkeeper changes.
"But we have done well and hopefully we can take that into next season and improve the goals scored."
