Tottenham, purveyors of a beautiful brand of football, also have a real edge and it's their English players who provide this steel.
In their attempt to stop the irresistible force that is champions-elect Manchester City, they put in two challenges which, taken in isolation, were both worthy of red cards.
Watching the game in its entirety — with access to every angle inside seconds — there was never a feeling that Spurs were trying to stop City with brute force. The poor challenges were isolated and the referee was in control.
However, looking at still images of the three big challenges would tend to suggest all could, or even should, have resulted in dismissals.
