Wales suffered relegation to League B thanks to a winning goal from Karol Swiderski, falling to defeat in their final game before the World Cup.
They had their chances, though, particularly in the first half as they cut through Poland's spells of possession, but couldn't make it count in front of goal. Daniel James found himself clear through on goal, but spurned the opportunity instead of testing Wojciech Szczesny or putting it on a plate for Brennan Johnson.
A moment of madness in the first half saw Wayne Hennessey almost let a pass from Joe Rodon slip into the back of the net for an own-goal, but both players' blushes were spared. It summed up Wales' night though as Poland looked more comfortable and made it count just before the hour mark, with Swiderski dispatching following a smart assist from Robert Lewandowski.
Gareth Bale's header rattled the woodwork in injury time which denied Rob Page's side of a late draw, but all focus now goes to Qatar in November.
