He's ok for slower La Liga games, but you need power and speed for these CL away games. Surely not an option yet.
Shit's bad when a 35 year old Messi moves quicker on and off the ball(when he tries) than Ansu does nowadays.
He returned from a 2 year injury. Give him time, we waited so many seasons for Dembele, can do at least one for Ansu.
Most of Ansus problems are fear of getting injured again, when he gets comfortable with his body again, he will return to his pre injury self.
Not sure what version of FM you have, It's 10/20 in mine.
But then again Busi has 11 pace so we know how accurate these attributes are.
You want a left winger,get Leao. Any other suggestions?
