Prödl also played the full 90 and again kept a clean sheet as Austria cruised to a 3-0 win against Slovenia in the Wörthersee Stadion in Klagenfurt (March 23), with West Ham's Arnautović scoring a brace.

Ivan Strinić made a terrible error, passing the ball straight to Carrillo, who fizzed his effort past a helpless Danijel Subašić from just outside the area after just 12 minutes.
La Blanquirroja scored again in the second-half, and then went down to 10 men with a quarter of an hour remaining, but managed to hold on for victory.
Craig Cathcart got onto the pitch for the first time since the Hornets' home draw with Brighton & Hove Albion in August, as he continued his return from injury away from the club.

Dodi Lukebakio and Obbi Oulare showed their potential as they helped Belgium's Under-21s to two wins from two.
The Belgians defeated Netherlands Under-21s in a 4-1 friendly victory in De Vijverberg, Doetinchem (March 23), with Oulareopening the scoring with just three minutes on the clock. He headed into an empty net, after Dutch goalkeeper Justin Bijlow failed to deal with a set-piece delivery, getting the Belgians off to a great start.
Lukebakio assisted the Belgian Red Devils' second goal, setting Dion Cools up to score - albeit unintentionally. The winger dribbled forward and was challenged by the Oranje defenders, with the ball ricocheting off Lukebakio and into the path of Cools, who lived up to his namesake and prodded the ball under the Dutch keeper under pressure.
Lukebakio also got himself on the scoresheet as Belgium Under-21s defeated Hungary 3-0 in their UEFA Under-21 Qualifier (March 27).
