Energy plus discipline
Although the increased strength in depth has enabled a certain amount of tactical versatility, there are some principles to this Wales team that will not be compromised upon. The Nations League offered an opportunity for Giggs, and later Page, to experiment with the squad and the system, with variations of 4-2-3-1 and 3-4-3 formations being used. However, the consistent element in each shape was the presence of a defensive midfield double-pivot, with this safety precaution placing an emphasis on the wide players to push forward at every opportunity and provide service for the height of Kieffer Moore and Gareth Bale in the penalty area.
But there is much more to Wales than just playing the ball up to the target man, and with a non-negotiable approach to playing the ball out from deep positions, the creativity of the likes of Joe Allen and Ethan Ampadu is used to good effect. With Daniel James, Harry Wilson and David Brooks all in equal contention for a place in the attacking third, there is a formidable amount of pace in this team, and the high-energy system will cause problems for even the most talented and disciplined of defences.
