England manager Gareth Southgate made a tactical gamble as he changed to a three-man defence for Tuesday's Euro 2020 last 16 clash against Germany at Wembley. Southgate had played with a back four in England's three group matches, but he opted to switch his system to match up with the German formation. Manchester City right-back Kyle Walker lined up alongside John Stones and Harry Maguire in an England back three that also started their World Cup semi-final defeat against Croatia three years ago. Kieran Trippier came into the side at right wing-back, replacing Jack Grealish, while Luke Shaw started at left wing-back. Bukayo Saka was part of England's three-man attack with Harry Kane and Raheem Sterling. Chelsea duo Mason Mount and Ben Chilwell had been self-isolating for the last 10 days. Mount was named among the substitutes but Chilwell was absent from the matchday squad. Germany boss Joachim Low made three changes from the 2-2 draw with Hungary in their last group game. Ilkay Gundogan was only fit enough for a place among the substitutes after suffering a head injury. Timo Werner, Leon Goretzka and Thomas Mueller came into the side, with Leroy Sane and Serge Gnabry left out.
