United boss Jose Mourinho said he was unable to say whether Lukaku would be fit for the Wembley showpiece with the Blues on May 19, although early indications are that the frontman should be available. He still wants to go. "We know that. I think he will do well at Arsenal".
Trips to Swansea and Everton will likely define which division they are playing in next season, but their fate may yet go down to the final day of the season, at home against champions Manchester City.
"I hope it is not something that keeps him out of a game in three weeks' time but I don't know". "I wait a bit more", Mourinho added.
United opened the scoring on 16 minutes when Lukaku's flighted cross was headed goalwards by former Gunner Alexis Sanchez, only for Hector Bellerin to deflect the ball onto the post, affording Pogba a tap in.
Lukaku didn't manage to score against the Gunners though he did have a decent performance in a game that saw Marouane Fellaini score the victor in injury time.
"I want him to stay, the club wants him to stay, I think he will stay, it is almost there", Mourinho said. "There were question marks if we would be strong enough to fight but the quality was good, the spirit was good, many players stood up".
However, the 30-year-old is one of Mourinho's favourite players for his physical presence in the opposition box and the Portuguese hailed his impact off the bench following Lukaku's withdrawal.
