We're 23 games into the 38-game Premier League season and Pep Guardiola's Manchester City have finally been defeated. Sunday's wild 4-3 defeat at Anfield was, in truth, a much tighter game than the scoreline suggests, the goals tally boosted by a couple of defensive errors and some excellent finishing.
Nevertheless, Liverpool's approach should be commended: they pressed in advanced positions to force those defensive errors at the start of the second half and City's upcoming opponents will consider this the template for causing City a fright.
The manner of Liverpool's success -- proactive, aggressive and positive -- is clearly good for the Premier League as a whole.
