The match between the Czech Republic and Wales seems to be the most competitive match today. The two teams are equally strong. This match is very important for both teams. The Wales team is stable, they play very defensively. Wales has 7 points from 4 matches and the Czech Republic has 7 points from 5 matches. Wales will be happy to share the points of today's match.
The game will happen next month, 10/08, right? This match will be an opportunity for Czech Republic to show a better performance than that one they had when the team lost against Wales in the round 3 of qualifiers by 1-0 in march. Judging only by that game I would say Wales is the favorite one, but since then Czech Republic has also showed some nice results, especially against Netherlands (2-0) and Scotland (2-0), both in Eurocopa.
And although this match is going to be very balanced, (correct me if I'm wrong) Wales may have a slight advantage in the bigger picture, because they have one less game in the group. So although both teams have 7 points, Wales will have an extra chance to play yet.
You are absolutely right, in fact the Czech Republic has always had an exquisite football, for its part Wales has Bale, and he is a player who at any time can define everything for his team, the speed that the player has is really one of the things for which Wales may seem superior today, yet in football anything can happen.
The level of European football is really high, I have seen other teams that continue to fight like Finland where they do not have stars but they understand each other as a team in an impressive way.
