Both. Sevilla did indeed have more of the ball after the goal but I reckon we had more of it beforehand. So, about even over the whole half IMO. I'm no rocket scientist though so take my observations with a pinch of salt
Btw, Redmond was nursing what looked like a rib injury towards the end of the half. Got elbowed in a challenge I think. Wouldn't surprise me if he came off at half time
I'm at the game. I wouldn't say that Sevilla are 'controlling things'. It's a pretty even game in terms of possession.
P.s. Stephens is looking very composed and has had a couple of great runs from defense into attacking positions (very van Dijk esque)
