Seems to be in a good spell. Xavi needs to put some real trust in him and start him in both league games until Lewa is back, otherwise there's also a real risk of him starting to get upset, since he's getting that good feeling back and you can tell he's happy (and more importantly good) on the pitch again. There's one thing to take care of him and watch him to not get injured, but at some point we're gonna have to take the risk and start playing him consistently again, to see if he can be a reliable option for us again, either at LW or ST.
No better time for it than now with Lewa suspended, Ferran being such a disaster and Depay gone. And especially since it's clear Ansu is getting that finishing touch back, but still lacking a bit of pace (hopefully not the new norm), so play him down the middle for these two games, and then at LW after Lewa is back. Would like to see Raphinha start in these games too (Dembele-Ansu-Raphinha), but it'll probably be Gavi-Ansu-Dembele at least in one of those games, and then Raphinha (and Ferran) from the bench.
