Brentford are not in good form these days, they have generally lost the matches in the last matches. Manchester United, on the other hand, has to not lose points in order to be among the top 5 teams. There is a 6 point difference between them and Tottenham and it will not be easy to close this point gap.
It is not easy to predict how many goals will be scored in this match, but I can say that Manchester United will win the match, this bet may be easier
Brentford are in bad shape, that's true, maybe something will change after this short break, maybe they needed a rest. Manchester United should beat such an opponent, but I doubt that they will be able to bypass Tottenham. I just looked at the first 10 teams in the Premier League and noticed that Manchester United has the worst attack, they scored the fewest goals, they scored and conceded the same number of goals 39:39, the guys want to achieve balance in everything. It is not easy to predict how many goals will be scored in this match, but I can say that Manchester United will win the match, this bet may be easier
However, there has been much better progress in Manchester United's performance recently so that they can compete to get tickets to Europe next season, a positive thing for improving the performance of the Manchester United team.
So I think they still have a chance to compete with Tottenham and Aston Villa if they are able to maintain consistent performance.
The match against Brentford shouldn't be a problem for Manchester United because these two teams are in different form, Manchester United is improving in performance and Brentford is in poor form in their last few matches, so this is an easy match.
