With Gueye having just come back I wouldn't pay him Saturday and I would have given him a couple of days of training as well.
He's run his arse off for us already this season and we are under no pressure to throw him back in. McCarthy can perform the same role adequately if needed.
Or main issue is the defence now, not centre midfield.
As for Lookman I wouldn't be surprised to see him start soon. Mirallas needs to watch his back though I agree on that.
