Lucas did, Masch rarely had a poor game.
You're probably thinking of his brief spell at West Ham
In 08/09, Alonso played the best season of his life, as did Gerrard. Mascherano was very, very good as well. Mascherano was never a problem, he varied between 'best pure DM in the world' and 'good DM.'
The way he left clouds some people's judgement of his time at Liverpool, but he went about it in the way I'd expect anybody to. He'd already given us an extra season and assumedly been told he'd be allowed to leave.
Thanks! I read some about his spell, it was only until the 3rd full year he played more than 27 matches. (25, 27, 34). I remember him being good at the end though.
