Arsenal defender Laurent Koscielny was left gutted after their 1-0 defeat to West Ham on Saturday but urged the squad to remain unified.
Declan Rice’s 48th-minute goal was the difference between the two sides on Saturday afternoon to condemn Arsenal to their fifth defeat of the Premier League season.
Arsenal remain fifth in the league table, but a resurgent Manchester United team is hot on their trails.
“We came here to win because for us the three points were very important, and next week as well to play against Chelsea,” Koscielny told the club’s website.
“We tried to play, we did well in the first half but didn’t have a lot of chances in the final third.
“We need to keep calmer in the final third and find the final ball, but in the second half we didn’t start well and conceded early.
“After that, we tried to push for the rest of the game, we had some chances and we didn’t score so it is difficult to come back with no points but we need two continue to fight to make the top four.
“Strikers sometimes have just one opportunity and they [are expected to] score, but sometimes you do it and sometimes it is more difficult.
“We are all together, it is not down to] one or two players, we are a group and we need to stay together and to push more for the next game.”
