Well if you are like less talented Messi you have potential to be world class. For me the only difference between Messi and him is that Messi has 20 percent more speed, and there for far more succesful dribbling, which puts him to great scoring positions often and only thing he need to perfect is finishing which he did.
So Halil got great tehnique and dribbling, and passing - long range also, he is at this point a great winger playmaker, but i hope he gets a bit closer to Messis finishing and dynamysm, he needs to develop his strength and speed and he will be great.
He is very close to David Silva level, 1-2 more years.
IQ. Intelligence, decisions.
You should look at that part also.
Alen is beautiful to watch at the pitch, and he adds value to the game even when hes not actually converting any chances or adding much to the winning of the game, he already has place on the pitch by that fact.
This is one of Halil's problems.
He always "played nice". When you see him running with the ball, he really looks elegant and better than 99% of other players.
But till now, more or less, nothing happens after his runs, dribbles, awesome actions.
A good thing is that he is finally playing in a smaller club, and imo, he needs to be the best or one of the best players in his new club, if he wants to raise his game to a higher level.
He needs to impose himself in a way that something actually happens after his actions.
Like 5-10 assists per Season, 5-10 goals, a few preassists etc.
Till now, he hasn't imposed himself (too much) either:
1. in Dinamo Zagreb
2. in young Croatian NT teams
3. in Croatian NT team (he rarely gets some minutes)
4. in Barcelona B
5. in minutes in Barca A
I don't want to sound as a bad guy, but he needs to turn from:
= did you see how I dribbled past 3 guys (and nothing happened after that)
= into: I assisted 10 times this season, scored a few winners, I am making the difference on the pitch
Ok, he is young, but he should impose himself more and more.
Sporting Gijon is a perfect opportunity for that.
