England manager Gareth Southgate and Netherlands counterpart Frank de Boer both received tactical advice from planes flying banners over their training bases on the eve of their Euro 2020 campaigns.
A plane flew over England's St George's Park base on Saturday, with the message "Most Croatia goals come down the left apparently" trailing behind it. The message seemingly was referring to Southgate's decision to take four right-backs in their original 26-man quad. England open their Euro 2020 campaign against Croatia on Sunday.
