Arsenal vs Brighton: Fabian Hurzeler makes key midfield decision after major deadline day departure and triple injury blow

Billy Gilmour completed a permanent move to Napoli, for around £15m, on transfer deadline day (Friday, August 30).

The Scotland international spent two years at the Amex, making 60 appearances in all competitions.

Gilmour’s move to Serie A had been placed in doubt after Matt O’Riley, a £25m summer signing from Celtic, sustained a serious ankle injury. This came six minutes into his Brighton debut – in their Carabao Cup win against Crawley Town on Tuesday.

O’Riley is set to undergo surgery but, despite his lengthy spell on the sidelines, Brighton decided to proceed with the Gilmour sale.

Brighton are without £100m of summer recruits for Saturday’s trip to Arsenal.

As well as O’Riley, Mats Wieffer, their £25m signing from Feyenoord, is also struggling with ‘a small issue’ following his encouraging debut at Everton. The Netherlands ace missed the 2-1 win against Man United and the Arsenal match arrives too soon.

German attacker Brajan Gruda joined for £25m from Mainz and is also hindered by an unspecified injury.

Ferdi Kadioglu, a £25m purchase from Fenerbahce, was paraded before the Brighton fans ahead of the Crawley cup win, but it seems he picked up a knock in training and misses the trip to Arsenal.

As expected, Hurzeler has named Jack Hinshelwood, Carlos Baleba and James Milner in the starting line-up at the Emirates – all of whom can play in midfield or at full back.

Time will tell how the exact team shape looks but here is the line-up in full:

Brighton: Bart Verbruggen, James Milner, Lewis Dunk, Jan Paul van Hecke, Joel Veltman, Jack Hinshelwood, Carlos Baleba, Karou Mitoma, Yankuba Minteh, Danny Welbeck, Joao Pedro

Substitutes: Jason Steele, Tariq Lamptey, Igor Julio, Adam Webster, Julio Enciso, Georginio Rutter, Simon Adingra, Yasin Ayari, Pervis Estupinan
