Manchester United manager Louis Van Gaal insists they can still overtake current Premier League leaders Chelsea despite a 10-point gap between both sides.
LVG's team's 2-2 draw at West Brom on Monday night has left them further in need of a positive result against Jose Mourinho's side on Sunday.
It promises to be the biggest test of the Dutchman's Old Trafford reign yet with United still to have faced any of last season's top four. However, the previous Netherlands and Barcelona coach remains relaxed and claimed his team's title hopes are not over just yet.
"That's possible however, difficult to say because then I'm arrogant," he stated. "However, I've done it tons of times."
"I think Chelsea and (second placed) Man City are another level. We've to see if we can beat them."
United remained in sixth place in the Premier League, 10 points adrift of leaders Chelsea, and Van Gaal admitted his frustration after individual errors had undone their good work.
