Rashford is 27 years old and can still play very well. The Englishman has the quality to be a player on a team of Barcelona's caliber. I find his transfer very logical for Barcelona. Marcus Rashford can't wait to play for Barcelona. How could he not? Many players dream of wearing that jersey. I hope he can succeed at Barça.
Yes Rashford is good enough to play for Barcelona but with the present Barcelona's squad I don't think Rashford is good enough to earn a stating role in the Barcelona's team.
This would be a different pattern of football than the one Rashford has been used to but he has the pace and ability to do just fine, I don't think Barcelona will use the buy option later, Rashford future will just be a decent premier league team, but I wish him all the best at Barcelona and I hope he proves me wrong.
