I mean he may be deceiving everyone for all we know.
Not sure myself why Valverde always wants to rush him back in.
With Arthur, Dembele etc he seemed to be willing to not rush them back as quick which is fine but with Umtiti it seems he wants him back as quickly as possible even though Lenglet has been fine for the most part. I mean I get Umtiti is good but sometimes it's better just not to rush it.
