Messi has scored 23 goals for Barcelona this season (La Liga 15, UCL 8):
Right foot: 11
Left foot: 10
Head: 2
Strange that he is mistaken to be very one-footed. His right-footed chip goals are famous I thought.
In terms of "shot power":
He's also the "strongest" player in footballing terms in my opinion. Optically he might not have huge muscle masses and consequently he might not win a fist fight against Ronaldo but on the pitch in terms of staying on his feet and evading challenges which is the relevant strength attribute for a footballer he's the #1. Who else does this?
