Haris Seferovic scored a hat-trick as Switzerland completed a scarcely believable comeback to thrash Belgium and reach the Nations League finals.

Thorgan Hazard scored twice for Belgium in the opening 17 minutes, leaving the Swiss needing four goals to progress.

Ricardo Rodriguez gave them hope with a penalty before Seferovic scored from close range and then smashed them into the lead.

Nico Elvedi headed in their fourth before Seferovic's third.

Switzerland will now play in next June's Nations League semi-final against hosts Portugal, England or whoever progresses out of France and the Netherlands.
