West Ham United's stars wore their Club’s sharp new Umbro 2021/22 Home Kit for the first time in Wednesday evening's 3-0 pre-season win over Reading.
The kit – available to buy online and in store now - is inspired by the iconic shirt worn by Paolo Di Canio and co at the turn of the Millennium.
The Claret and Blue Kit will grace the Premier League and Europe in 2021/22, as David Moyes’ men get set for their first-ever UEFA Europa League group campaign.
