despite the good head to head record being enjoyed by Barcelona it is been noted that since 2012 Bacelona has won manchester united 4times against manchester united 1.
This is true that Barcelona have had several wins over Man United , but I do think that this time around it's going to be a different ball game, looking at Man United form and Changes over the years in both clubs. Barcelona had this incredible coach Guardiola and players, Lionel, Xavi, Iniesta and more compared to what they have now, basically a lot of things has changed which could affect the result too.
Yes, it's true that Manchester United can now be said to be in a prime position considering the last 3 games they were able to win, maybe even then Barcelona will accept Manchester United's victory gracefully, and maybe in the minds of the Manchester United squad, Barcelona is not a solid wall that difficult to penetrate or torn down for now.
They have played tough matches in the Premier league and currently the third place Manchester United team. It will be very true to say that it will be a difficult match for Barcelona. Manchester United will do their best. The team that passes the round advances enough to go to the championship, but everyone is eagerly waiting for the match right now.
