Manchester City saw an unlikely hero emerge from their galaxy of superstars to make a potentially defining contribution in their pursuit of an unprecedented fourth successive Premier League title.
Pep Guardiola rightly acted with caution when he removed keeper Ederson, with City leading 1-0, after he suffered a nasty blow to the head in a heavy collision at the foot of his post with Tottenham defender Cristian Romero.
Ederson, who had a problem with his eye, did not look happy with the decision - taken upon advice from the club doctor - but his manager was perfectly justified, not just acting in the best interests of the Brazilian keeper but also because he has complete trust in his replacement Stefan Ortega.
