Leeds United's Liam Cooper, Stuart Dallas and Mateusz Klich complete international action

Leeds United captain Liam Cooper helped Scotland to victory on Monday night while Stuart Dallas suffered a heavy defeat with Northern Ireland.

Mateusz Klich was also in action for Poland as he stepped off the bench to help his side to a 2-1 win over Bosnia and Herzegovina.

Cooper was handed a start by boss Steve Clarke as the Tartan Army travelled to face a completely changed Czech Republic outfit.

The hosts were forced to call up a complete separate squad for their second Nations League encounter in four days after a coronavirus outbreak hit Jaroslav Silhavy's team.

The Czech's were only able to name two previously capped players for the clash but took a shock lead on the night through Jakub Pesek after 12 minutes.

Scotland, though, hit back before the half hour mark through Lyndon Dykes before a Ryan Christie penalty completed the turnaround in the second half to secure a 2-1 win.

Leeds utility man Dallas also completed 90 minutes as Northern Ireland were heavily beaten 5-1 at Windsor Park by Norway.

Mohamed Elyounoussi opened the scoring after just two minutes before Paddy McNair pegged the visitors back four minutes later.

Norway then took the lead once again sixty seconds after the restart through Leeds-born Borussia Dortmund star Erling Haaland.

Alexander Sorloth - son of former Elland Road trialist Goran - then bagged twice before Haaland struck his second of the evening to complete the scoring.

Klich, meanwhile, was a second half substitute for his country as he completed 22 minutes in a narrow victory over Bosnia.

The trio will now return to Thorp Arch to begin preparations for Saturday's opening day Premier League clash with Liverpool at Anfield.
