It might be a bit early to judge, but I think Benitez was a good move for Liverpool. They're playing better football, and I think he may be up to building a great team for them, something Houllier never looked like doing.
Oh, in a Q&A after a small presentation or something in Dublin, Mark Lawrenson admitted that he thought Houllier was a "chancer". He also admitted that he wouldn't say that on Football Focus.
