Not that I doubt Leo's loyalty to the club but he is not exactly a dumb ass to leave now, when the things are not very bright anymore...... coz if he does, he would be tarnishing his legacy for good this time. There would not be a looking back, there would not be even a slightest chance left to shut the stupid stupid mouths who say that all of Leo's glory was the result of Xaviesta's greatness.
No, not only is he not a dumb-ass (aside from a pre-mature retirement announcement from Argentina in the spur of the moment of course) but he also truly loves the club to do some thing like that. I do not need any other proof of his love towards the club after his gesture, to not celebrate the penalty against Leganes
