Image: Thomas Partey headed home from Emile Smith Rowe's corner against Aston Villa Before long, there were in-person visits too. They started what Buttgereit calls a "study group" over Skype. Matthew Benham, the club's owner, and Rasmus Ankersen, their co-director of football, were eager for the pair to bounce ideas off each other. Jover, 40, started out as an analyst at Montpellier, where he helped the French outfit claim their first Ligue 1 title in 2011/12, and went on to have spells as a set-piece specialist with the Croatian national team and Brentford before his move to Manchester City.Īt Brentford, he came to know Mads Buttgereit, another set-piece coach who was working for their Danish sister club Midtjylland at the time. His replacement has brought a fresh perspective and he has a wealth of experience behind him too. The Swede built strong foundations defensively - in fact no Premier League side conceded fewer set-piece goals than the Gunners last season - but he left considerable room for improvement offensively. At Arsenal, meanwhile, Georgson's impact had been mixed.
