Brighton & Hove Albion had the third-best defensive record in the Premier League last season with Jan Paul van Hecke as a pillar of the back four.They have quickly adapted to the Dutch international’s £52million ($71m) departure to Tottenham in June by assembling a range of options in the middle to make themselves hard to score against once more, and to give head coach Fabian Hurzeler scope for rotation in the Conference League.Canadian international Promise David — an unused substitute against Aston Villa on Sunday after a season-long loan move from Union Saint-Gilloise with an obligation to buy — has joined the strike force following Danny Welbeck’s move to Chelsea.Attention will switch to the overall look in midfield in the rest of the summer transfer window, with Carlos Baleba about to complete a £70m switch to Manchester United, and also possibly to the right wing if Liverpool increase rejected offers of £50m and £60m for Yankuba Minteh.The heart of the back four, meanwhile, is a refit already ticked. The extent of the choices open to Hurzeler was evident in the matchday squad for the 4-0 trouncing of Villa in Brighton’s first league fixture of the season. Luka Vuskovic, bought from Tottenham for a club-record outlay of £46m in July, impressed on his debut, albeit against dishevelled visitors, who had midfielder Ross Barkley operating as a makeshift No 9.Vuskovic partnered long-serving skipper Lewis Dunk on his 300th Premier League appearance for the club — the first Brighton player to reach that landmark. Olivier Boscagli shifted to left-back to deputise for Ferdi Kadioglu, who was ruled out by a minor injury.Lewis Dunk made his 300th Premier League appearance for Brighton on Sunday (Mike Hewitt/Getty Images)Pascal Struijk and Michael Svoboda, also signed during this summer’s window — from Leeds United and Italian side Venezia for around £18m and £7m respectively — were on the bench without being called upon by Hurzeler.
