Probably wouldnt work. Barcelona changed their methods when Rinus Michels went there as manager (contrary to popular belief, they have not 'always played like that'). He proposed that the first team, down to the youth team all played the same system - They didn't win the Champions League (their first ever) for another 20 years... One good reason to get him though is that they want him as a replacement for purpleface at the Theatre of Shit
