Middlesbrough boss Aitor Karanka said he hopes Manchester United win the title after his side lost to Jose Mourinho's men on Saturday.
Karanka was previously Mourinho's number two at Real Madrid and said it was not easy to face off against his old friend.
"It was difficult for both of us because we have an amazing relationship. We both wanted to win," Karanka told the BBC.
"I hope they are at the top of the table at the end of the season and we stay in the league."
The result kept Man United 13 points back of leaders Chelsea, though it leaves Karanka's Teesiders just four points above the relegation zone.
