I think Manchester United don't need much to plan for Premier League now, they should plan more for Europa League matches. Manchester United drew in the first leg match so the second leg match is really important for them. If Manchester United cannot enter the field with full strength in the second leg match, they will be far behind Real Sociedad. This season Manchester United is performing somewhat well in the Europa League so we expect Manchester United to have a good chance of winning the Europa League title at least this season. Now if Manchester United plan equally on both the Premier League and the Europa League and take both more seriously then a good performance in either one will surely have a negative impact.
I can't say whether they have performed better in the Europa League or not, all I can say is that they have always had a mixed performance and even that was a very bad performance. They drew the first leg, but that's an advantage because in the second leg they will be playing at home. But the problem is, sometimes for Manchester United, whether they are playing at home or not, when their game is in disarray, they will play badly. I can't say what will happen in the second leg.
Well if not for the penalty they committed I will say they really did well to some point but they really need to improve on that, the way Manchester united use to play and seeing them draw from away against Real sociedad was a great result and I want to believe they will do even more better In there home else Real sociedad will knock them out of the Europa league and I think this is the only hope Manchester united have this season so it will be nice if they utilize it because there is no hope of qualifying for Europa or conference league.
