Brentford manager Thomas Frank says Manchester United were 'unbelievably lucky' in their 3-1 win on Wednesday night.

The Red Devils were outplayed in the first-half but ultimately ran out with all three points.

"Unbelievably proud of my team," Frank told BT Sport. "We are the smallest club in the Premier League, Manchester United the biggest.

"We destroyed them in the first half, they didn't have a sniff, three huge chances and there could only have been one winner of this game. They are unbelievably lucky. I know all the stuff about taking chances. They changed the system against little Brentford.

"One of those nights, fair play to David de Gea, if we get those chances again one will go in the back of the net. Our intensity killed them, we showed that in the first half, we played the Brentford way.

"Of the three goals, the second is most disappointing and difficult to come back from. The way we smashed them in the first half was fantastic, so proud of my team."
