A lot has been written on this forum on how fast players are over-powered. This is the case in my experience as well.
I think the key problem here is how fast players run with the ball at their feet. We all know that players are slower with the ball than without it and this has been implemented in the game accurately enough. But players with lower dribbling stats can still run with the ball at incredible pass once they are in behind i.e. when they don't have to go past the defender.
In my opinion players with higher dribbling should be quicker running the ball than players with weaker dribbling even when they don't have to beat a defender (It doesn't seem to me that this is implemented in the game). The only exception to this should be players who have "knock ball past opponent" ppm (should probably be renamed to "knocks ball on when on the run" if this is to be implemented) ala Henry, Valencia and Bale.
A lot of times in real life you see players like Darren Bent, Welbeck and even Balotelli at the euros, get the ball in behind the defense but get caught by slower defenders because they struggle to run comfortably with the ball. A recent example was Balotelli chance against England where his first touch was perfect but he struggled to run with the ball and was caught by John Terry!! Only exceptional players (dribblers) like Messi are rarely ever caught because their control of the ball while running is so good that their pace is only affected minimally.
