oh yes read every thing.same old boring topic . Messi was and will never be a player like suarez or a Sanchez who will run for their life to get back the ball , but to say that he never tracks back and help's the team in defending is laughable .I have seen many times that Messi tracking back a long way, I will give you few Examples , One vs Aguero when he was playing for Atleti , were leo ran from one half to other, and won the ball , Messi running back and tackling Di maria in 2011-12 season . Another was in last season ,Don't remember against which team, we were wearing pink kit ,And the one vs against Roma in his return match after injury few weeks ago , Now please don't come up with the arguments that i mentioned only 3 instances , he has done it several times . !! More than that he walks in the middle of a match at time's which people finds irritating , i would relate that to His Growth deficiency disease . people with such disorder can't run all the time like a sanchez or suarez does . Messi has several times vomited in the pitch . His body doesn't cops with such extreme work rate . People need to under stand that . No one is 100% perfect
