I don’t agree he was ever slower than Rodri, even now I’d back busquets in a race but even accepting he was, he had great anticipation, better positional sense, used his body as a shield/obstacle far better and could make recovery tackles, Rodri is substantially inferior in all of those areas. He was also playing in arguably the greatest club side ever, they didn’t lose the ball, they won it back further up the pitch and it was revolutionary football, nobody knew the weaknesses back then because they couldn’t have enough of the ball to find them.
Just naming players for different sides who were also fairly slow doesn’t suddenly mean Rodri’s lack of pace isn’t an issue. In our team, right now, in his position, you need to be more mobile than he is and his lack of mobility is being exploited every game.
