Just because Chelsea failed to win against Brentford does not mean it should be underestimated when Chelsea against Manchester United today, because Chelsea will also try to maintain its position in the standings at this time because Manchester United's points are very close to Chelsea and if Manchester United wins, then the top four standings will belong to Manchester United.
I think Liverpool, Manchester City, Manchester United and Crystal Palace will probably win their respective games. I hope they are the favorites in the game, but about the Chelsea vs Manchester United game I think some doubts will definitely arise.
Chelsea at home is expected to win and it seems right after I've reviewed some of the opinions of people. Even I think their fan base in this thread is huge, but I think Chelsea are looking good at home. Manchester United is good, but the conditions in their dressing room are not pleasant after the coach's decision to play without Ronaldo.
