He's very good at long range passing and shooting. His leadership abilities and his drive are excellent, which is probably why people overrate him.
Other than that he's good, but that's it, good. He's also a coward, a hypocrite, and although I don't know him personally everything points to him being a bit of a cunt.
Over the years I've read and heard loads of tripe about him, from people talking about him in world class terms to people suggesting he's the most likeable footballer around. If they win the league I can't imagine how unbearable it will be, St. Stevie guiding the paupers to victory through blood sweat and tears. Makes me sick.
Xavi's hair gel has got more footballing ability than Gerrard.
