Manchester United caretaker boss Ralf Rangnick says they cannot risk taking Brentford lightly tonight.

It will mark United's final home game of the season.

Rangnick said, "You could even see that in their [Brentford] first game, I remember watching it on TV," Rangnick told United's in-house media.

"They won 2-0 against Arsenal, they won two or three weeks ago 4-1 at Chelsea, at Stamford Bridge. We had our problems in the first game, in the first half. We could have been 2-0 down and we could only manage to change and turn the game in the second half.

"This will again not be an easy game for us. As I said, very important [end on a high at Old Trafford] both for the fans but also as a boost for the new season. For everyone it would be good to get three points in this game."
