La Liga is now very good, Madrid has Finally got some great players, now the squad is much better, Barcelona didn't have enough to do much , because Lamine has so much money that they can't even buy more players, so the other teams in La Liga have been reinforced, that means that things will be more interesting and more balanced.
There are concerns about Rashford moving to Barcelona because of their different style of play compared to the teams he's played for previously. He might need more time to adapt, but I hope he can become an important player for Barcelona, even on loan. The idea of bringing Rashford to Barcelona is certainly surprising, especially since I've forgotten who the previous English player to play for Barcelona was.
What he has to get used to is the speed that Barcelona demands of him, it is a team that has that as a strength, so in view of this I think his main task is to be able to adapt to a Hansi Flick who has a fully integrated team, perhaps Rashford will take 2 weeks to 1 month to be able to reach that level, MU does not play with that style, and perhaps they will put him to play from the 70th minute onwards to see how he performs.
