Erik ten Hag is confident Manchester United will bounce back from their latest defeat and go on to seal "vital" Champions League qualification at the end of the season.
United lost 1-nil to Brighton on Thursday courtesy of an Alexis McAllister penalty in the ninth minute of injury time at the AmEx stadium.
The win moved Brighton back into the top six and left the Red Devils with a four-point advantage over fifth-placed Liverpool, though United have a game in hand.
"We have every time in this season when we had a defeat, we bounce back," Ten Hag said ahead of Sunday's trip to West Ham.
"So, I count on my players, I count on my team. We have to do it again.
"There is no time to stay in this (disappointment), so in one hour we go onto the game against West Ham United. All focus on that.
"We prepare for them, we make a good plan, the players have to take responsibility and they will do. I count on them.
"They have to do it and they can do it because we have the evidence in the season.
"Every time when we had disappointments, they bounce back."
United have not won a Premier League game at any of the top nine teams.
They have collected just one point from a possible 27 on the road against those sides.
