We'll see who Pep will bring against Barcelona and regardless of what it is this match will be interesting to see
The last time Barcelona met Manchester City was in 2016 in the Champions League group stage. At that time Barcelona lost to Manchester City with score of 3-1, but after that the two had never met if I'm not mistaken. So for this friendly match, I hope that both of them can be serious enough to play their best players and also with interesting game strategies.
Despite the fact that Barcelona won City in their last game when both of them met in pre-season ,right now if both teams should use their full squad to play that game, still I'm not gonna risk my money to (bet) on Barcelona to win Manchester City because the strength of Barcelona as at now ,is no way to be compared with the strength of City's squad at the moment.Then looking at it as being a friendly match they're not going to use their full squad , so the bottom line is that the outcome of that game would be base on the team that got good young player, I do believe is likely going to win the game.
