It seems to me that you are the one being emotional and writing nonsense. United were big favourites in this game and the odds for them to win were 1.59 (I know this for sure because this outcome is in my multi-bet).
And they lost the first half. Yes, in the end they achieved victory but it was another garbage game that does not show the team's progress.
After having good results in last two games now things are turning positive for the Manchester United because their confidence level is high, and their players are feeling positive for their future at this club this brings good change for them, and we have good performance from them in second half which give them win.
No doubt before start of the game Manchester United was favourite for this game, and they were not good in first half, but we have completely different team in second half which allow them to have win.
Fenerbahçe is completely different club but after having draw against Porto things are looking impressive, and we can expect another surprising result from Manchester United with draw/win are looking good.
Well, if you are so confident in United that you will place a bet, it will be nice if your confidence pays off: +150% for one bet is very satisfying. But I'm not sure that such a bet is justified - United are not so bad that they are underestimated greatly and a bet on them would have great value. I backed them against Brentford but I can now say it was a weak pick.
I have feeling placing bet on Manchester United for the Europa Cup game which is going to play in Turkey is surely risky more than placing bet on them against Brentford because Fenerbahçe is big club in Turkey, and recently they are having good performance with things are favourable for them to have won or draw because Manchester United is under development and things are surely not easy while they needed good time for having good results against big clubs.
Both teams are having equal chance of win with for me Fenerbahçe have better chance because they are better team then Manchester United specially while they are playing at home.
