You know whats funny, I reckon every permanent manager since Moyes (King Carlo aside) would've had us relegated after taking over from the fatman.
Each of them would've stubbornly stuck to their way of playing because thats their "philosophy".
Credit where its due, Tory Frank came in, tried to play how he wanted, realised these players cant do it and adjusted to get the most out of the players that he could.
Thats called good management.
Will he play like that from now on, most definitely not. But he temporarily compromised his own footballing beliefs to suit the situation, which is very Carlo Ancelotti. All while being personable and (I hate this phrase but...) buying into the club and its ethos.
