It wasn't so much an improvement, but more a complete transformation from Liverpool.
And it is probably no exaggeration to suggest this was precisely what English football so desperately needed, to ensure the Premier League doesn’t become another Manchester City procession. No one at Anfield will be thinking they’re back in the race just yet; 10 points isn’t just a gap, in a season which will be a ridiculous war of attrition, it is a chasm that still looks too vast to make up against a side with such fire power.
Yet for Arsenal, Tottenham and Chelsea, this small sign of vulnerability from Pep Guardiola’s side, the manner in which their defence was exposed ceaselessly by Mohamed Salah and a Reds forward line that was full of desire and belief, will offer real hope of a real contest at the head of the table.
