Pep Guardiola will seek a summit with referees' chief Mike Riley after another moment of controversy left Manchester City's title ambitions hanging by a thread.
City squandered a two-goal lead during a pulsating clash with Tottenham and that means they could find themselves 12 points behind Chelsea by the end of Sunday after the leaders have played Hull.
The game, however, swung when referee Andre Marriner failed to award a penalty when Kyle Walker pushed Raheem Sterling in the back as he shaped to shoot; Tottenham promptly went up field and made it 2-2 through substitute Son Heung-min.
