Januzaj was technically a level above Garnacho, but it seems he had other issues which stopped him hitting the heights he possibly could have done. Whilst I like Garnacho, I do have some reservations on exactly how good he is or will be. I think he's a bit one dimensional at the moment, and needs to add some variety to his game, if he wants to become more effective and eventually be good enough to be considered a first team starter for us. Especially if we keep spending money and improving the team. What he does have is pace and tenacity. I like how he keeps on trying to go at players - it just feels like teams have got his card marked more recently and are managing him much better in games. Even just recently against Arsenal in pre season, he had no impact and probably touched the ball 2 times in 45 minutes.
Do you really think Garnacho is one dimensional? He's acceleration is electric, and he uses it to great effect to go past on the outside or dribble on the inside - that means that he is by default two dimensional at the very least - unlike Robben who did his 99% of the time cut inside but to great effect. Garnacho is also quite clever in that when he's running at speed, he's rarely going full pelt, so he has that extra gear which makes it very difficult for defenders to react. If the ball seems a little far from his feet and the defender commits, Garnacho has the ability to get there by accelerating further, which causes the defender to think again or foul him. That is a dimension that Rashford unfortunately is lacking but Ronaldo was a master of.
I also think Garnacho has pretty decent playmaking abilities - much more so than most teenage wingers.
He's very efficient inside the box because of his close control dribbling.
He's decent on the counter because of his speed, but I think his top speed will improve significantly when he develops more physically - he's already very fast.
To me, he's certainly not one dimensional.
As for comparing him to Januzaj - most footballers would dream of having Januzaj's career - he's a very good footballer. Ultimately, he probably lacks that little bit of explosiveness to be a great winger, but his technique and dribbling are class. I think Garnacho
may surpass him, and probably has more in his locker, but it's a long way yet. Their United careers thus far are pretty similar I guess - promising first seasons for both.
