​[BBC][Getty Images]The third Unai Emery era begins at Aston Villa.The first was the march to the Champions League in 2024 and the second the run to winning the Europa League in May.The third could prove to be the defining moment for Villa as they look for long-term success and to build on what Emery has already achieved.Yet patience will be required after a summer of upheaval during which key players departed and the transfer record was broken twice – first with Johan Manzami and then the £65m arrival of Nicolas Jackson from Chelsea.Villa needed to balance the books and Morgan Rogers’ £117m move to Chelsea helped that, but the exits are not purely down to financial constraints.Release clauses triggered the moves of Youri Tielemans and Lucas Digne, while Villa will be happy to move on from the agitation of Emi Martinez’s desire to leave, now the goalkeeper finally has his wish.The money brought in for Ollie Watkins from Al-Hilal was something Villa could not turn down, with Emery conceding it was crazy to get £50m for someone 31 in December. Ezri Konsa wanted his move to Arsenal.It all means Villa have lowered the average age of the squad – which was the second highest in the Premier League last season – and reduced the wage bill.That was one of the priorities going into the summer and they can be satisfied, even if Emery was not prepared for the wholesale nature of the departures and it was not the plan.Jackson, Manzambi, Joao Gomes, Ibrahim Mbaye and Taylor Harwood-Bellis are likely to form the core of the new era, with the potential of Brian Madjo seemingly unlimited.Close to £280m has been committed, but it will need time. Emery likes to ease his players in so he can trust them implicitly to deliver his methods and demands.He must accelerate that process with a number of new players and that could mean some missteps.Villa were ready for change. Now they must adapt to it.How are you feeling about Villa’s squad now the transfer window has closed until January?Get in touch with your views here
