Thanks for all the responses. Considering that matches can be moved around for TV in many countries and mess up flights booked a long time in advance (and the fact that acquiring tickets for any particular game can be problematic) I think I will drive to Dover and take the ferry to N. France/Belgium and spend a long weekend dipping in and out of Belgium/Netherlands and the Gladbach area of Germany, where I have many friends. We should be able to attend several matches at different levels and possibly in three different countries. A certain City fan lives in Belgium too....
