Sadio Mane tormented Chelsea as the Liverpool forward struck twice after sparking Andreas Christensen's dismissal in the champions' 2-0 win, while Son Heung-min scored four as Tottenham crushed Southampton 5-2 on Sunday.
RB Leipzig showed no signs of missing Timo Werner on Sunday as they strolled to a comfortable 3-1 home win over hapless Mainz in their first Bundesliga game of the season.
More than $250 million spent trying to catch Liverpool, and Chelsea is still far from the level of the Premier League champions. Two months since Chelsea finished 33 points behind Liverpool, a 2-0 loss on Sunday to Jurgen Klopp's side showed just how far the gap is to be bridged. For all the attacking options now available for Frank Lampard, the Chelsea manager was let down by a reckless foul by defender Andreas Christensen and yet another blunder by goalkeeper Kepa Arrizabalaga.
