Messi's been pretty poor this season. I think we may have seen the best of him between 2009-10. He's lost a yard of pace IMO
Dunno if ur sarcastic or serious but im still gonna comment on this because I want to add to the last thing you said.
I disagree with you that he has been poor, 17 matches 22 goals and 11 assists, hes been quite good.
I did however notice the thing you mentioned last, he seems a bit overall slower and less quick as he was, but he rarely even runs at speed and at defenders alot like he used too so its hard to really say..
Might be that he has a bit more weight or maybe its just that hes not really running at defenders and with the ball much, slowing the play down alot compared to before when he used to rush a bit more.
Doesn't really make sense that he would be much slower and less quicker than before hes 24.
