Wales scraped past Estonia with an unconvincing win in Tallinn to keep hopes of finishing second in their World Cup qualifying group in their own hands.
Kieffer Moore poked in from a yard out to give his attack-minded but defensively shaky side a half-time lead.
They became increasingly disjointed in the second half and were fortunate to preserve their lead as Estonia’s Erik Sorga and Mattias Kait missed good chances.
The hosts, ranked 111th in the world, pressed gamely for the goal which would have earned them a second draw in a month against Wales, but Robert Page’s men clung on for a crucial victory.
The Czech Republic’s 2-0 win in Belarus keeps them second in Group E, ahead of Wales on goal difference but having played a game more.
With Belgium almost certain to secure the only automatic qualification spot as group winners, Wales are looking at the play-offs as their most realistic route to a first World Cup finals since 1958.
They are already effectively guaranteed a play-off place thanks to their success in the Nations League, but finishing second in this qualifying group could secure a more favourable draw in that knockout stage.
Wales finish their regular qualifying campaign with home matches against Belarus and Belgium next month, while the Czechs host Estonia in their final fixture.
