Surely alves had a better kicks-to-goals ratio than RC? I think he adds something extra, and i found RC always seemed to hit it into the wall whereas alves at least gets it on target and the rebound causes some danger for the defence.
Rafa is a quality freekick taker though, but is very inconsistent.
I say Henry from close, mainly because every free kick he has taken for us since being here (not many) has been on target. When you get it on target theres always the chance of a spill, so...
