What do Wales need to qualify?
A dream scenario would be for Wales to win all four of their remaining matches, as that would guarantee a place in the top two of the group, and with it a spot at Euro 2020.
But that's a tough ask to say the least.
History shows countries finishing in second spot in five-team qualifying groups end their qualifying campaigns, on average, with 15 points from their eight fixtures.

As Wales currently have six points with four games left to play, it looks as though they'll need three wins at the very least to qualify, potentially drawing the other game, unless there are a few surprise results elsewhere.
As for the Slovakia game specifically, lose and Wales will face a monumental task to qualify via the regular format. Their hopes would be all-but ended. So it appears to be a must-not-lose game rather than a must-win, although three points in Trnava would be enormous for Giggs' men.
Seven points could even be enough for Wales, for example, if they were to draw in Slovakia, lose to Croatia and then win their final two games, as long as Croatia defeated the other big guns in the group, which would allow Giggs' side to sneak into runner-up spot.
What about the Nations League?
Let's not forget the Nations League as it could yet come to Wales' rescue.
