There's no player in history who's a far better dribbler than Neymar. He's practically undefendable in one on one situations and regularly takes on 3-4 players at once. He maybe has some shortcomings in regards to upper body strength, balance, etc. but those are points of criticism of a very high level. He's much more than doing some stepovers. His anticipation, awareness, control etc. are beyond world class and most importantly he dribbles with purpose unlike players like Denilson, Ben Arfa, etc.Robben is a far better dribbler. Bit of a weird opener. Though I suppose that would start the debate of what good dribbling consists of. Some people equate Robinho doing 12 stepovers in a row as the pinnacle of dribbling. Int hat case, yes Neymar is a better dribbler. However, take your point that Robben can only cut inside, why do you think that even though any fullback that ever faced him would probably hammer into his brain, that he will cut inside, was left staring at the ball flying into the net. That's because Robben is an amazing dribbler and even knowing what he will do, you wont see it coming. Other than that, saying Robben can only cut inside is selling him short massively.
I don't think Robben is a better player than Neymar, I'd say they're in a similar league with Neymar edging it slightly. Truly world class, but not as good as Messi and Ronaldo. They're probably also 2 of the most disliked top players of all time.
Oh, and the poor man's Robben was a joke initially, but saying Neymar is not massively better than Robben is not trolling if you ask me. Saying he has worse hair than Robben, maybe..
The same is true for Robben who's much more "straight forward" in his style. To me a bit closer to Messi stylistically. He also relies primarily on body feints and is quite similar in how he attempts to catch the defender on the wrong foot and utilize him losing his balance a bit to open up small lanes for his shots, passes or dribbles. Neymar's dribbles being fancier than Robben's makes them neither better nor worse. Resultwise they're pretty close with Neymar edging it, IMO.
Both exceptional players, mind.
