Another thing is Barcelona right now is concentrating more on the La Liga title. So, I am not very confident about winning against Manchester United. Manchester United on the other hand has shown some significant improvements.
maybe Barcelona is very concentrated on La Liga. now is another opportunity they can't ignore for both of them after their UCL exit.
now Madrid also appears dominant in La Liga. if Xavi does not take advantage of the opportunities that exist, Barca may also lose hope for the La Liga trophy.
I still hope Barca will win the game against United. although team-wise we can see United looking better.
@Pandu Geddon I believe that
Barcelona players will be distracted, because now De Jong has been rumoured to say that he wishes to leave Barcelona and join Manchester United. Furthermore Manchester United players are getting better and better with each game that they play, hence I expect them to defeat Barcelona easily and progress to the next round.
