Chelsea's ability to tear up the form-book is nothing new, particularly where arch rivals Tottenham Hotspur are concerned.
Even so, the reversal of expectation at Wembley which saw the Blues beat Spurs 2-1 immediately ended the "crisis club" chatter that had followed the shock home defeat to Burnley on the opening day of the season surprised many.
Minus the services of skipper Gary Cahill and experienced midfielder Cesc Fabregas, both lost to suspension via needless red cards picked up against the Clarets, the portents didn't look good for Chelsea and their manager Antonio Conte in particular especially given the way Spurs had clinically won at Newcastle in their season opener.
