I for one am thrilled about having Raffa back in the PL! I hope he and red-nose picks up again right where they left it. Let the fighting begin! :)
He's always been very loyal to and passionate about his club (Liverpool) and the things he has said in interviews about opponents, or their fans, is brilliant, and as a Liverpool fan I would always have huge amounts of respect for the Spaniard.
He's a really good manager and I think he will do very well with Chelsea, their fantastic squad filled with Spanish speaking players.
It's a shame though for his sake, that no matter what he do he'll probably get the sack at the end of the season. But I do hope Benitez is back in the PL to stay.
In fact, if Mancini for some reason was sacked at the end of the season (not saying I want that to happen), Benitiez would be one of three or four managers I think would actually make us even better.
