Manchester United boss Erik ten Hag admits their top four hopes are in the balance.
United sit nine points off the top four.
"It will not be decisive for the end of the season but in the Premier League, [there are] seven or eight teams competing for those four [Champions League] positions so we can't give points away," Ten Hag said of today's clash with West Ham.
"You need every point and you have to fight for every point because the points will be more expensive when you go to the end of the season, so we have to make sure, to put us in the right position in the month of February, we have to win on Sunday."
