Punching a ball in the back of the net a'la Maradonna will get you labelled that. For all the greatness Maradonna had he is known by millions around the world for being a cheat. Messi is following the very same path, just with less ability.
I don't doubt he will be in Spain in a couple of seasons. He doesn't owe us anything as it is. Fans of other football teams say this to rile us clearly, but it doesn't bother us
.
Actually, up until the 05/06 season RVN did track back all the time and help, it's when he became 'lazy' that we sold him. As for Ronaldo, he's our quickest break, so we leave him forwards and clear our positions towards him as he's a good target man, however, Ronaldo does also help cover the overlap at RB when required.
Liverpool won because they played better, they got through on credit, not because the other team played poorly. Credit where it's due.
