I honestly couldn't complain with Sigurdsson starting yesterday. Gomes hasn't had one of his "majestic" games really since probbly Arsenal way (the sort of game where he seems to just look effortlessly above the rest). I think he looked tidy at times at Spurs and Palace but he really struggled in the derby. Sigurdsson has done well off the bench. Yesterday has probably taught us there's a world of difference between coming off the bench when we are winning to starting a game though.
There are some issues emerging from yesterday and that threat in behind was a big one. I've seen some takes that Iwobi was ok first 20. I really disagree, he was involved but he wasn't impressive. He as picked out on 3 or 4 occasions and did very little with the ball. He is primarily responsible for our lack of threat in behind, as he just doesn't want to run in behind, kick it out of his face and go in on goal like Richarlinson does.
Southampton started by doubling up on James, then crowded him with 3 or 4 as they knew his switch to Iwobi was pointless. He can't play wide in this team in my view, he can only really play inside and knit the play.
Bernard is also not a runner in behind really. Gordon is the closest to Richarlinson we have, so thats where I would look.
I really don't want to hate Iwobi, but he really does test the patience.
