Barcelona's patented preaching to the irritated "You can take our ball ... but you can never take our freedom!" shouted absolutely nobody at all on Wednesday night, as that would be the sort of demeaning national stereotype to which WWLTW has categorically never played. No, sir! Ahem. It is a shame that nobody shouted such a thing, however, as it would have made a superb point about Celtic's defeat of Barcelona. In an even more exaggerated dominance than usual, the visiting Catalans had 83.6 per cent of the possession at Celtic Park. They completed nearly 1000 passes, more than six times the amount that the home side could boast. It is an approach for which Barca have been lauded extensively by football observers everywhere. They hold the ball for three straight minutes in midfield and the "ooohs" and "aaahs" start on Twitter, bouncing from viewer to viewer to viewer to viewer to viewer like ... you can probably finish that simile yourself. Tiki-taka has long since stopped being a tactic. It is now a cult, protected by its servants with feral vigour rarely seen outside of Twilight fans (who themselves are rarely seen outside). What we weren't allowed to learn this week... The hilarious power cut in Braga on Wednesday was a gigantic missed opportunity for football. Instead of waiting 10 minutes to resume under 'normal' conditions, the match should have been allowed to continue. The true greatness of the likes of Robin van Persie would have been properly tested
