I'm very optimistic about Manchester united performance tonight as I think they wouldn't want to continue with a loosing streak. They know too well that the fans are not really happy about their recent performance and they wouldn't want to continue that way coupled with the fact that they want to get a trophy this season aswell.
Burnley do not really look to me as tho they would win although am not trying to rule them out but I know they are aswell not going to make it easy on Manchester united as they will have to earn it more like they will need to be at their best to be able to defeat Burnley because Burnley will be having the home advantage over Manchester united as the game will be hosted by Burnley.
Erik ten hag will most likely stop at nothing to win this game as a win in this game will really go a long way redeeming his image and that of the team at large. It may also have likely effect on his job too , this is my personal opinion tho. Because it's usually that when a coach suffers too many losses the next action in line is usually for the team to relief him of duty.
It looks like they can already forget about trophies, after 5 rounds they are 9 points behind City, and although this is only the beginning of the season, I see no reason why anything should change for Manchester United in the near future. Manchester United should beat Burnley today, but I'm not sure about Ten Hag's team, their defense is too bad. Manchester United spent a lot of effort in the match with Bayern, and Burnley rested at this time and prepared for the match, this could also affect the result today. Of course ten Hag will want to win today, because so far the results of his work look too dubious.
