His finishing has declined but i think thats due to him not getting so many chances as before,we can argue he wont get to 2012 level but we are a different team too.
With neymar,suarez and in the future munir here his finishin could get a bit better but thats it,there is no need for scoring a million goals anymore his build up play ,movement and pressing are far more important now.He will still be the most valuable player for the team.
Michael Jordan won i think 5 mvps of the league scoring ridiculous amounts of points but Chicago couldnt win anything against Pistons,then he made a team around him to suit him and became the best player of all time,and this Barcelona are going in the right direction,Messidependencia will stay but there will be others to score and u can shut down messi in the box but you cant shut him down when he takes the ball from busquets and raki on the run.
Messi is evolving.
Deal with it times are changing and its good.
