Worse:
Free thinking - players are seen to be going rogue if they break from the system and the instructions briefed for their area of the pitch. In the event something goes wrong in their area of the pitch due to them trying to take the initiative, they will be summarily chided and you won't see that same 'mistake' again as they go back to playing on tracks as the remit demands. Expression is steadily eradicated in this manner.
Creativity - So much more of what you see now is rehearsed to an inch of its life. As impressive as those chains can be, the uniformity is predictable and not exciting unless executed at blinding speed and technical quality. Again, a player going rogue and thinking on the hop can disrupt the entire chain and then things can become disjointed until order is returned and the system is dominant again. Technique isn't better, but sequencing of plays/routines/drills is a magnitude of order superior.
Fitness - a con as well as a pro. Hard running drones are harder to beat than a bunch of highly skilled, lower fitness individuals. A lot of technical brilliance is being filtered out of the game in this manner where those who cannot keep up with the demands and repetition of the press are liabilities to the system. A player like Riquelme would be in deep doo doo coming through now.
Long range shooting and lower odds strike attempts - Risk aversion is so high that taking shots on from 30 yards out is now looked down upon. Obviously, an art form takes a tumble when few practice those things anymore.
#10's - all the greatest of all time have been #10's. It is supposed to be the genial position on a football pitch. These days there very, very few #10's active, and the little we do see are heavily marginalised. Riquelme; M Laudrup; Del Piero; Baggio and so on and so forth; what do they look like if they came through in this age? A #10 is more praised for his pressing from the front than he is for his mercurial offensive abilities now. Coaches will pick a hybrid of the two every time over a purer, more skilful (better) #10, I think.
