You're making a massive mistake to confuse talent/ability with actual success in 1st team football at a club like Barcelona...Deulofeu has done nothing in 1st team football in the time he's been given, nothing...And to suggest this coming year he'll surpass a player like Tello or Pedro who have scored, dominated and won trophies is preposterous...A little perspective, don't fall into the hyperbole vortex
Same applies to the Neymar fanboys...At least Neymar has had success against 1st team footballers but both him & Deulofeu will need to do more than rely on their talent/skill, they will need to work their ass off...and even then, success is not assured
If Deulofeu gets the same kind of treatment that Pedro got once he first came into the team, I think he will succeed. Pedro, IMO, has been a player who has been successful bc of the team, not bc of his ability. What he doesn't have in ability, he makes up for in work ethic and tactical positioning. But that only takes you so far, which is why he isn't lighting it up anymore.
Like I said, if Tito trusts Deulofeu the same way Pep trusted Pedro and really gives him a fair shot (which he should), I just think he will overall develop into a better player than both of them in time. I'm not saying he is now, but by this time next year I wouldn't be surprised if he wasn't at least of the same quality while I expect him to be higher.
But you are right, without a fire and hunger to improve and develop, to do the extra training while others rest, both him and Neymar will flop. It's hard to measure this since we don't see what they do away from the pitch week in and week out. I guess we will just have to see.
I just see a lot of potential in Deu, and with effort on his part and confidence on Tito's part, I think he will really flourish.
