Brentford came from 2-0 behind to draw 2-2 away at Leicester City while Manchester United lost 2-1 at home to Brighton last weekend.
When asked if this is a good time to play Manchester United, Brentford boss Thomas Frank said: “I don’t think there is an ideal time. In general I don’t believe in if it’s a perfect situation to play them in or a bad situation to play them in.
“But one thing is for sure, they’ve got a new manager, a brilliant manager, I think he’s done a fantastic job in his earlier jobs, so they’re very interested in doing everything they can to make it a success with the players.
“They lost the first game, so if you lost a game the most common response (is) to really want to improve and do well. So it’s going to be extremely difficult tomorrow.”
