Where does this bollocks come from?
Did you not see the Arsenal game where we got done by a team using exactly Lyons tactics and formation? Did you not see the Norwich game, Wolves, Spurs, United, Southampton?
Lyon are better than all of them. There's every chance we lost just as easily in a 433.
Pep doesn't make these changes for a laugh, he does it because we've got massive weaknesses that good teams have exploited all season.
I cannot understand the deluded arrogance to think we would have been untouchable in a 433 when we have seen its not true all season long.
