Celtic were widely praised for their display but Schuster was quoted in the Scottish Sun as saying: "I'm fed up of seeing these type of matches.
"We saw it last year with Chelsea. It was a very bad example for football and it is regrettable that they became European champions.
I mean, it's almost like they're cheating, isn't it? It's just flabbergasting that a team with inferior players would have the chutzpah to attempt to clog the six foot passing lanes of a team that has worked so hard to perfect those six foot passes and is highly unlikely to try anything else.
Personally, I don't think Herr Schuster has anything to fear. The bastard knows better than that. The fact of the matter is that the tactic requires a defense that is just as difficult to execute as the passing game it intends to stop, PLUS a rip-roaring counter-attack in order to be successful. If it were that easy all of Barca's league opponents would do it.
If you ask me, I'd be fed up if everyone employed Barca's tactics. The game would be supremely boring. Vive la difference.
