Wales are guaranteed a World Cup qualifying play-off spot at least after Spain won 1-0 against Greece on Thursday.

The Spain victory saw Luis Enrique’s men secure a top-two finish in Group B.

And that confirmed Wales, currently third in Group E, as being guaranteed qualification for the play-offs by virtue of their efforts in the Nations League.

No matter what happens in their final two group games, Wales will have another shot at World Cup glory in the spring to fall back on.

But that doesn’t mean their fixtures against Belarus and Belgium aren’t important.

What you need to know before Wales play Belarus and Belgium

A second placed finish in their group would likely see Cymru drawn at home in the playoff semi-final against one of the three worst second placed finishers or three teams who will qualify via the Nations League.

However, if Wales were to be pipped to second by the Czech Republic, Rob Page’s men would be one of those away teams, travelling to one of the six best second place teams in the one-legged semi-final.

In order to secure that second place, its likely Wales will need to pick up four points from their two home games against Belarus and Belgium.

Wales and the Czechs are currently tied on 11 points, with Wales having a game in hand.

However, due to goal difference and the remaining fixtures, the Czech Republic are probably favourites for a second placed finish.

They play Estonia at home on Tuesday, and will likely pick up three points and add to their goal difference.

Meanwhile, Wales host Belarus on Saturday, and will hope to do the same for their own goal difference.

That will mean Rob Page’s men will likely need to claim a point against Belgium on Tuesday to secure second place.

There is also a small chance Tuesday’s game could be a winner takes all encounter for a place at the World Cup.

In the unlikely event that Belgium lose to Estonia on Saturday, two wins for Wales this international break would see them top group E.

How to watch Wales’ World Cup qualifiers

Both games will be shown live on Sky Sports and S4C.

Wales take on Belarus in the easier of their two games at 7.45pm on Saturday.

They will hope to claim all three points from that encounter and set up a huge clash with Belgium on Tuesday.

That will also be a 7.45pm kick off.
