The remaining 3 slots for the European Cup in Germany will probably go to Poland, Ukraine and Greece.
But Poland against Wales is also not an easy thing. But I think Poland can definitely get rid of Wales.
I also agree that Poland will beat Wales but it will be tough especially as Wales are quite stubborn and with Poland having the advantage of most of their players present, it will be difficult for Wales to penetrate them when they meet on the 26th. Poland are just above Wales with three points and I know that eyes will be on both Robert Lewandowski and Gareth Bale to deliver both their teams. I'm also in favor of Poland winning that game by a slim margin.
