I welcome Arblaster back into the first team reckoning. As a player type he'll be after Norwood's role in the team. They share some of the same attributes, but Arblaster is a more modern player. Despite not being a exceptional athlete, he'll be better than Norwood in shielding the ball, making space for himself and advancing with the ball. While Norwood is a static playmaker, good at making himself available and having the vision and composure to distribute, rather than getting dispossessed, Arblaster can get on the ball, invite the pressure, but still get away or even skip past a challenge, and then set the team up for an attack.
I noticed Wilder spoke positively about Tom Davies, and in my mind we need to make room for Arblaster to get a proper chance in the team. So I'd try to get rid of Norwood and Fleck in January, and let Arblaster compete with Souza, Hamer, Davies, Brooks and Slimane for the spots in central midfield. If we're going to bring in one more central midfielder it would have to be one with genuine, proven quality, or someone who we think could be a real future asset.
