If you look at the history of the meetings between the two teams, indeed Barcelona has better capital because they always win, while Manchester United loses more often when they meet Barcelona.
but we can't compare with the previous meetings because everything has changed a lot, especially the players and coaches who will make the game different from before. And it will be a very exciting match because both are in top form and also have good results at the end of matches in all competitions, especially at Manchester United.
Looking on head to head all Manchester United fans can't forget about Lionel Messi goals at Champion League final season 2008/2009 and Barcelona won 2-0 goals. Manchester United performance in this season more quite well better due Erik Tan Hag has impressive performance and 20 won of 27 matches become fantastic record for first manager at last several season.
I doubt with Barcelona performance in Europe League, due managed first La Liga standing position and have three points left with Real Madrid still not sure having consistency performance because facing bigger team. Failure totally in Champion League and bad record achievement when bigger team opponent like Inter Milan and Bayern Munich are reason why doubt with Barcelona in Europe League.
