So, I bought this game today and have been playing it for a few hours. I'm really enjoying it. But, can someone please explain the World Tour set up please?

Basically, I started in Wales, and I played the two 5 a-side matches, the one Panna match, and then played the 5 a-side tournament to progress to Stage 2.
In Stage 2 however, I completed the Freestyle match, Last Man Standing Match, and Panna match. Now I have a selection on 3 separate 5 a-side tournaments + another tournament in London.

My question is, do I have to complete all the tournaments to unlock the tournament in London or do I just need to win one tournament to make it to Europe (Stage 3)?
