messi's 1st effort was blocked by GK, then he tried 2nd time on the loose ball, who cares if he's shooting or passing, the point is at that moment tevez was offside

there's nothing special here.

and of course CK has no offside, cause at that moment the kicker is already parallel to the bottom line. but any subsequent palying is subject ot offisde rule.

i don't see your point
