Saturday was the 7th time I've watched us in France, the only trouble I'd seen previously was people being tear gassed in Nice by the CRS, the night before we played at Monaco in 2004 & I'm not certain that was football supporters involved. Earlier that year we'd played in Marseille in the UEFA Cup, the authorities there seemed convinced they'd be trouble due to what happened with the England fans during the World Cup 98. Their wasn't any, Liverpool supporters & England fans are like chalk & cheese. So what happened at Wembley for the Final of Euro 2020 is irrelevant.
Also nobody forced Paris to take the final at 3 months notice. We've been in 3 finals in 5 years, so saying they only had 3 weeks to plan for us being there is ludicrous. I've no doubt Chelsea & Man City would have had similar problems to what we encountered.
I've never seen any trouble between us & Real Madrid supporters, not in Kiev 4 years ago, home & away in 2009 & 2014, or when we played at Atletico in 2008 or 2020 or the 2019 Final.
Using waist high tripods & multiple check points, opposed to full height turnstiles at Wembley. Saw 66% of the footfall we had for the FA Cup Final a fortnight before take up to 2.5 hours longer to enter the stadium. When you buy a ticket for a Champions League final & spend a small fortune, it shouldn't be a lottery whether you get in or not & you shouldn't be left sweating whether you get in for kick off.
