For me it would be a no brainer and I would pick Fernando Mendoza. Too bad we don't know how much much passing and crossing influences the corner taking. The only thing working well is that a 6star player could get some more MoM awards. As a 6 star you get less exp but MoM is, if I am not mistaken, always the same bonus for all players, so he actually gains the most exp. I especially use this for my 7 star corner kick taker.
