That's somewhat sobering but I still think he's young enough and skilled enough that with confidence from his manager, he'll come good.
As that bloke says, he's got all the attributes but just can't link them together and maybe that's to do with sporadic appearances and a desire to try and impress the manager, knowing that he'll be benched again if he messes up.
A bit like Tel towards the end of last season, where he felt the pressure to perform and suffered for it.
RDZ seems to have the ability to instill confidence in his players and make them believe in themselves, so if he can do that with Sav, he may actually prove to be a bargain in comparison.
We'll just have to wait and see but it's not the first time a fanbase hasn't rated a player who's gone on to do well elsewhere.
Remember what Juve fans said about Kulu and Bents?
