Pep Guardiola said Kevin de Bruyne is helping Manchester City become "a better institution" after the playmaker put in an inspired performance to help his side outclass Tottenham for a 16th successive Premier League victory that stretched their lead to 14 points.

Ilkay Gundogan, in for the absent David Silva, headed City in front from a corner after 14 minutes and the only surprise was that it took until 20 minutes before time until man-of-the-match De Bruyne's powerful shot extended their advantage.
