Yes he will be presented for Lazio, no surprise there. Kind of surprising they will be doing it right now though as Lazio hasn't paid neither the deposit nor the contract buyout fee to Valencia. I am sure they will but if by chance they don't there could (not could there will) be problems.
Sad to see Piojo finally go but I think Valencia made a good deal. They got some good money from it to spend on some other players. As long as Valencia doesn't get rid of their true star, Mendieta, they will be alright.
