We must find focus to get back on track, says Van Nistelrooy
United are nine points adrift of leaders Arsenal and their next three league games are against Newcastle, Liverpool and Arsene Wenger's champions.
"We are not in a position to be thinking about catching people," Van Nistelrooy said yesterday. "We are nine points behind after 15 games, so we shouldn't look to what anyone else is doing we should just be concentrating our efforts on winning our own matches and take it from there.
