Manchester United boss Louis van Gaal admits his side might face tough competition to make it into next season's Champions League.
Having failed to beat Arsenal at Old Trafford, the Red Devils will have to feature in the play-off stage before making it into the group stage of next season's Champions League.
And the Dutchman says it will not be easy.
"You can say we are unlucky because it is the third deflected goal in a row and falls in our net," van Gaal is quoted as saying by the BBC.
"But I have said it is not unlucky to the players. You have to force luck by finishing games. We are one hour better and 1-0 ahead.
"You see Arsenal want to come back so you have to stick together and be compact.
"I have said Arsenal have maybe the best team but Chelsea can finish the game, which Arsenal cannot do and we can't either. That is important. This season we have only finished two games. It is a pity.
"We have not yet qualified for Champions League. It is always stressful as you can meet opponent who is halfway through a season already. It is not so easy.
"I am satisfied we have set our goal and reached that. From what I have seen of the fans they are pleased. But I want more as manager. Next year we will fight for more.
"[David De Gea?] The same thing as I have always said.
"It is a process for David De Gea. He will not leave us easily as we have a great club and he wants to participate. But he is Spanish. And he could go to a great club. It is difficult for him to decide."
