We should extend his contract now. He is incredible for his age. Just turned 23 and is already one of the best around, Hes about 5/6 years away from the normal prime age for a centre back.
Presuming when he signed he agreed a five year contract (I'm not sure he did but most top players seem to do so these days upon joining a new club) then I think it'd be best waiting another year. After Salah had been here a year he signed again with an extra year on top of his deal, but if we had held out another year and then got him to sign, we'd have an extra year on top of what we do now, and that would have been right after winning the European Cup as well. I suppose you can't predict the future though and nobody was against extending his deal after his amazing first season.
Nowadays I don't think you really want your top players going down to the final two years of their deals. That was when I started getting concerned with Gini, and the same thing has happened with Salah, Mane too I suppose. Anyway, those are all players at different stages of their careers, Konate's only just turned 23 and hopefully we can find a way to keep him here for the best years of his career because if he carries on like this under Klopp and beyond he could be one of the best central defenders of his day.
