Nope.I agree in a limited sense. Yes both had moments of good play and haven't good enough overall, especially lately, and both need to be out.
The only difference I see is that Lo Celso is a skilled player in a bad fit while Lucas is not skilled at all.
But overall both need to go.
Lucas is now a bonafide club legend, gives his all every single game, makes an immediate positive impact in the vast majority of games he plays, and scored 4 vital goals across two of our biggest games in recent history. He can stay in the squad until his legs go, as far as I'm concerned.
Lo Celso looked a bit busy for about 2 months and has done absolutely nothing of note since. So you're right GLC needs to go, at least.
