Gerrard did well, but to us, the real brains behind the coaching was Mick Beale who ultimately left Villa and went to manage QPR. I still think he could end up back at Rangers.
Gio is a former player and I have huge respect for him.
Thankfully he got us in the CL as already the doubters are out in force, not happy we lost the league last year etc etc.
People need to remember the headstart Celtic have had while we were having to climb back up the divisions and no European football etc.

Son I have no idea, I am a long time admirer, perhaps he just had the season of all seasons last year and this one is less than normal for him.
The midweek game will perhaps give a clue, especially with him being subbed at the weekend with Richarlson (not sure if that is his surname!)
