Focusing only in the Europa league would be a great and nice idea but to me the Europa league, I don't see Lyon as threat because Manchester united will qualify for the semi finals no matter how hard Lyon try and the premier league looks tough for Manchester united but that doesn't mean they will lose all the match I doubt if that will be possible as a matter of fact I don't see Nothingham forest winning Manchester united despite there form, I know the bookmakers will pick Nothingham forest, Newcastle and Manchester city as favorite but it is going to be a deceit because it won't happen.
In Europa League I also still believe more in Manchester United's ability this season even though their opponent is Lyon. But in the Premier League I still have a little doubt for Manchester United to win the match at Nottingham Forest's home because during this season the team has developed quite well in the Premier League. But if Manchester United are able to get one point when playing at Nottingham Forest's home, it is certainly a great result for them although not so good for the home team who are struggling in the top three of the Premier League standings.
I think with level of quality in Premier league compared to Ligue1 apart from PSG, I believe Man Utd would have an edge over Lyon, though soccer analyst and pundits would wouldn't vouch for Man Utd to win having consider their present form and injury to some of their key players, Man Utd knew how important winning Europa league would qualify the team for next season European competition now that their chances of qualification through the premier league is very slim the team would definitely capitalize on Europa league Cup, meanwhile their match against Nothingham Forest is unpredictable from my own point of view any of the team can with that match.
