Switzerland completed a remarkable comeback in a penalty shoot-out following Monday's dramatic 3-3 draw in Bucharest, where Yann Sommer emerged the hero after saving Kylian Mbappe's spot-kick.
Having opened the scoring and seen Ricardo Rodriguez's penalty saved by Hugo Lloris early in the second half, Switzerland found themselves 3-1 behind with 15 minutes of regulation time remaining.
But Haris Seferovic netted his second of the game in the 81st minute before Mario Gavranovic's last-gasp strike forced extra-time after cancelling out Karim Benzema's brace and Paul Pogba's stunner.
Sommer then stepped up with the decisive save in the shoot-out after extra time to send Switzerland through to the quarter-finals at a major tournament for the first time since the 1954 World Cup.
"It is amazing man," Switzerland captain and man of the match Xhaka – who refused to rule out a move to Jose Mourinho's Roma from Arsenal – told beIN SPORTS.
