LONDON (AFP) - Jack Grealish scored his first goal for Manchester City as the English Premier League champions thrashed Norwich 5-0, while title rivals Liverpool extended their perfect start with a 2-0 victory against Burnley on Saturday (Aug 21).

Grealish marked his home debut following his British record £100 million (S$185.6 million) move from Aston Villa with a close-range effort to double City's lead in the first half.
