Brentford midfielder Vitaly Janelt was floored after Manchester United's late fight-back on Saturday.
Scott McTominay jumped from the bench to score twice in injury-time for United to win 2-1.
We played a very good game, and at 90 minutes we were leading at Old Trafford. Then, in five minutes, they turn around the game and win 2-1," said Janelt.
We have to finish a counter or a set-piece to make it 2-0; that's the only thing I would say we can do better.
It's nice to have a good performance but obviously we want the points. Sometimes I don't care if we play s***t, as long as we get three points. We can turn it around together."
