Obviously we are going to exercise it.
Lo Celso is in a tricky position because the guy who did a lot of the courting to get him in is gone. But due to circumstance (injuries, rated as unfit by Poch early in the season, Poch's sacking). He has not gotten the minutes he and we all expected. But he needs to soldier on, show that he is committed and maybe have a talk with Mourinho so both parties are on the same page and it will work out.
Jose knows what a talent he is. He just needs to get on a run of form and it will become clear. And some runs need to start off the bench.
What Gio and Tanguy need to understand is that they are new, barely speak a word of English and are the players Jose will know the least about. We are also 3rd in he form league at the moment since the new manager came in and it's downnto them to find their feet in a new boisterous league, a new way of living and lifestyle, new surroundings and they need to own it when the moments come.
It's not as bad as it looks or seems. Both, along with Sessegnon picked up injuries here and there at the worst time for them to settle and by the time Gio was back we were in turmoil. It's not about integrating them at present, it's about getting things settled as a unit again and then you can experiment, you build from the back in football and Gio + Tanguy simply need to wait until they can be utilised in what is now a squad game.
