Harry Wilson and Alex Iwobi put the Cottagers on top before Richarlison pulled a goal back.

The hosts had fallen behind to Yasin Ayari’s goal but levelled through Samuel Chukwueze before Wilson’s late winner.

It was the first time Wales had scored seven goals in a game since April 1978.

Gabriel Gudmundsson’s 94th-minute own goal proved the difference.

Harry Wilson, Sorba Thomas and Brennan Johnson scored as the Dragons fought back.

The Cottagers were 2-1 victors in a Premier League contest which had a dramatic finish.

The Dragons will play Finland, Iceland or Ukraine at home in the semi-finals of the play-offs in March
