Even when manchester united was not in a good shape and i think that manchester has a big chance to win the game. Manchester united is slowly moving up again. The perfomance is not yet reached its best performance but i think that if the current performance from MU was equal to the barcelona. I will not even try to underestimate manchester united for now caused by it can make barcelona going back anytime.
Manchester United and Barcelona are not different. How do you consider a club at second position in La Liga is weaker than a club at a fifth position in Premier League. If you don't consider Barcelona are stronger than Manchester United, you should consider them are at a same.
Chance to win for them is 50 - 50 for both clubs and I am exciting to see their matches in Europa League. In history, they met each other sometimes in Champions League and usually Barcelona did not bring happiness to Manchester United except a match United won with a long distant shot from Paul Scholes.
that reminds me when people were picking barcelona over frankfurt and did you know that barcelona lose against frankfurt?
that's the story of last year but that's still worthy to take some lessons if any team in europa league was also very strong at this moment too.
United even can lose when they met smaller teams than Frankfurt. About performance stability, both Barcelona and Manchester United are very bad in recent seasons.
