The visitors lead the table by virtue of goal difference, with both sides having won three and drawn two of their five games so far, a sequence that includes the goalless draw between the pair back in November. On that day Wales defended heroically and cancelled out the World Cup quarter-finalists, who badly misfired. A similar performance as well as a touch of attacking quality would surely give them a great chance here off pulling off a famous result.
And Chris Coleman’s men come into this off the back of arguably their best showing for many years, going to previously unbeaten Israel and putting them to the sword in a game in which they dominated for long periods and were simply a class apart after going ahead just before half-time. Gareth Bale may have had his critics at Real Madrid in recent months, but he was in unstoppable form and provides by far the biggest threat for the Welsh here on the night he wins his 50th international cap.
Belgium also come into this having gone to Israel and won, with an early Marouane Fellaini effort proving the difference. The Manchester United star will be missing here, however, along with suspended captain Vincent Kompany, so there could be vulnerabilities to exploit although their squad still possesses talent in abundance including in-form Aston Villa striker Christian Benteke and Premier League winners Thibaut Courtois and Eden Hazard.
James Chester and Aaron Ramsey should be fit for Wales, but Paul Dummett, Ben Davies and James Collins are all absent through injury, leaving them lacking in defensive cover for this clash which will inevitably take place at a highly atmospheric and partisan Cardiff City Stadium.
