Everton’s Hill Dickinson Stadium, five days before the Premier League opener against Crystal Palace.Kiernan Dewsbury-Hall is on stage at an event hosted by podcast and media company Men in Blazers, candidly discussing the lessons learned from last season — and how a first qualification for European football since the 2017-18 season agonisingly slipped from their grasp.The club’s chief executive Angus Kinnear has since said that campaign is viewed as a “failure” by American owners The Friedkin Group in an interview with BBC Radio Merseyside. And many of those involved have spent the summer trying to understand what happened.“I had a lot of time to think about it,” Dewsbury-Hall says. “(There were) a lot of lessons learned. The main one is never get complacent till the final whistle of the final game.“Put in the same position again, I don’t think that we’ll be making that mistake.”Listen to Dewsbury-Hall and you get the sense of a side ready to right some wrongs, but Everton’s manager David Moyes struck an altogether more cautious tone in a chat with Sky Sports, his first with any media this summer.“We’ve got a long way to go and want to do an awful lot more (in the transfer market),” the Scot said.So, how ready are Everton for the new season?The Athletic has followed them at home, in Germany and Scotland, speaking to key figures to get a sense of how they are shaping up.“It’s been one of the longest pre-seasons, because it usually takes maybe 10-14 days of hard sessions,” left-back Vitalii Mykolenko says of the Premier League returning one week later than usual after this summer’s World Cup.“It’s already the fourth week of training. But it’s good for us. It’s tough, but there is nothing silly. Everything is for a purpose.”The Ukrainian was speaking to The Athletic from the team’s Oschberghof training base in Germany’s Black Forest. The setting is lavish but remote, which is part of its appeal for clubs such as Everton.Oschberghof is an hour from Switzerland’s Zurich Airport, boasts three renowned golf courses, and players are able to cycle down the hill to use the two pristine pitches provided by local club SV Aasen. Serie A champions Inter were visitors in July, while Spain used it ahead of their victorious 2024 European Championship campaign.
