Maybe, just maybe, if both Rakitic and Busquets stop jogging and starts running to give more options to pass, maybe Arthur can have legs until the end of the game. Our midfield looks a one-man sometimes, with only Arthur building the attacks, moving without the ball, going up and down to participate.
Arthur had these same problems whenever i watched him with Gremio. Improving this guy stamina must be number one priority for him right now.
