He won't be power trained, he will be too slow to PT next season as he moves out the 26-29 bracket and into the 30-31 bracket. He has not gained 1 quality point this season, started 107 (45) and now 107 (31). So at best he is a reserve. I'd rather save my greens for a younger player or scout, If I'm going to power train anyone old it will be Papaleo. As much as I like Zidane and his contribution. The arrows are pointing to the exit door sadly because 4* these days at July Fourth seems insufficient for reserve for July Fourth when 5* players can be signed cheaply on my server. I kept a 34 year old 4*104 GK this season because it was for reserve purposes and reserve GK's don't play that many games anyways and I would of had to pay him 2 years wages ($14M) to kick him out lol.
As much as I want to keep Zidane I think he will have to be sold.I wish this game would expand to 25 man squads because players like these can stay around.
