After the long break from the World Cup, the main aim of the teams will be to perform well in their respective leagues. As Barcelona now want to win both the La Liga and Europa League titles, it will be very difficult for them. Barcelona's main goal now will be to maintain consistency in La Liga. And if the Barcelona players can maintain their dominance in La Liga then they will try to win the European title. However, the match between United and Barcelona will be very competitive.
Now this break and coming transfer window is going to be vital for many teams and their performance into domestic leagues and European Competitions because as we are having updates many players are going to leave their respective teams which is surely going to have big impact on their performance and results in coming weeks.
Barcelona vs Manchester United is surely going to be a big match as right now Barcelona is having top rank in La Liga and Manchester United is badly struggling in Premier League with waiting for too many changes into their squad, hopefully things could be positive for them, and they will be able to have their best days back after many years of poor performance in all competitions.
