TBH I don't know. I genuinely believe as a club, we tend to overrate our youngsters far more than other teams due to our history of bringing through a few. I genuinely don't believe that Martial or Rashford had ever shown the type of talent that led us to reward them with the type of grace and money that we have. I would love for Garnacho to become a top talent, but in all honesty, it really isn't a guarantee like people want to make it seem.
In fact, I'd say, he scares me in some similar ways as Rashford and Martial used to. They were good in specific situations, but outside of those moments, when asked to do other things, they were always found wanting. In Rashford's case, he's has poor iq, poor dribbling, poor movement in the box, an inability to hold the ball and difficulty playing on the ground. His touch was always loose. As an attacker for a team trying to break down teams, outside of a few athletic bursts and strong shooting outside the box, he doesn't offer much. Martial could not play at all with his right foot, making him a completely liability when ever he wasn't given the space to cut inside. He wasn't a strong passer of the ball and struggled on the turn. His movement off the ball was horrendous as well. Not a good finisher either. Outside of using some dribbling ability to cut inside with his right foot, his impact on the game was pretty limited and barely showed signs of growing outside of a brief stint from in August 2020.
That's my big concern with Garnacho. What he has in his game is mostly confidence and being able to drive at the oppositon when given space. He's not a good finisher, cant really go on the outside, doesn't have a great touch, or have a good link up game. He may grow, but as a team, we need good quality now and one we can guarantee based on what they can currently provide.
