Kosovo's first competitive home fixture ended in a 6-0 defeat by Croatia that leaves them bottom of their World Cup qualifying group.
A hat-trick from Mario Mandzukic, followed by further goals from Matej Mitrovic, Ivan Perisic and substitute Nikola Kalinic secured a one-sided victory for visitors Croatia, who with four points from two games top Group I.

Ozan Tufan's header in the first minute of first-half stoppage time, from Hakan Calhanoglu's cross, reduced the hosts' deficit. Calhanoglu then brought them level in the 81st minute from the penalty spot, after Taras Stepanenko's foul on Cenk Tosun, leaving Turkey fourth with two points, the same total as third-placed Ukraine.

Hosts Austria held Wales to a 2-2 draw. After Joe Allen gave Wales a 22nd-minute lead, his Stoke team-mate Marko Arnautovic headed Austria level.
