You mean the one to Lenglet? Well a player who just comes from long term injury is bound to making stupid mistakes, the player feels unease at start, and stupid mistakes just happen. Also i don't really think he had that many bad passes? But i wasn't wachting the game with full concentration so i may be wrong. My impression wasn't that he made bad passes, but that his positioning was just way off (for reasons i have mentioned before), destabilizing the whole defense - and normally we have Pique as a whole game but especially defense leader, and you can't expect Umtiti to fill those shoes after not playing with his mates for the whole season. Normally i consider Umtiti to be a vocal and leading figure (with fine positioning also, not perfect) but as said, he just came back, it wasn't up to him to organize our back line, actually it would have been Lenglets job i guess. Thats also a concern i have stated here before. Our board members here praise Lenglet a lot and want Umtiti sold, but as said several times, we have to remember that he is playing alongside Pique as leading figure, and Lenglet jobs is secondary to Piques. Umtiti has already showed that he can be a leading figure, managing a back line and maybe even a team from behind, lenglet hasn't. Im not saying he can't, but he hasn't shown it yet because it hasn't been necessary for him to learn it, just like Pique didn't when we had Puyol around. And it even took a lot of time for Pique to take a leading CB position at the club, before it wasn't him, but Mascherano, and now he has finally taken the staff (all tho he did do it in big games before and for some longer periods).
Finale note, i wouldn't read to much into Umitis performances right now. He is rusty as hell, like anyone would be in his situation. And all tho Lenglet has been amazing, but he hasn't yet shown what Umtiti did pre-injurie. And it would be a huge mistake to sell or witch hunt Titi because he has played a few bad games after a long term injure. just my 2 cents
