I saw a video of Rashfords Training sections few days ago and I can not agree any less that he is going to do even better at Barcelona, it is a very different environment from what he had at Manchester United and the experience is going to be different to so I will go with the idea of judging him with his last Manchester United performance and think he will be doing same with Barcelona, here he will be willing to show value so that he can earn some recognition and Importance to the team so it is obviously a different mentality all together.
I'm not sure if Rashford would shine if Barcelona were to sign him. He's been training hard, but his recent results have been a bit dip. Logically, if he could make a significant contribution, Manchester United would retain him or even make the move permanent at Aston Villa. So, honestly, I'd be skeptical about the player, even though he was once a highly rated player. I find him stubborn and a bit egotistical. If he can't change his attitude at Barcelona, it will all be for naught.
I think Rashford is not a Barcelona quality player. Barcelona management wanted to give him a chance but I think this chance will be wasted and I don't think they will buy him.
There are players in Barcelona’s bench and academy who are better than Rashford and I think it would’ve made more sense to give those players the opportunity instead.
I hope the Rashford transfer is the right decision for Barcelona.
