When will Jurgen Klopp learn that his Liverpool defence simply isn't good enough?
Reds fans were desperate for the German to make defensive reinforcements in the summer transfer window but, much to everyone's frustration, he said no.
Instead, Klopp signed Mohamed Salah - who has been a superb addition, admittedly - for £38 million and Alex Oxlade-Chamberlain, who he didn't even need.
Andrew Robertson was brought to Anfield, too, but the Scottish left-back isn't the calibre of defender required for a side with title ambitions.
Klopp's mistakes in the summer came back to haunt him against Tottenham on Sunday, because every goal was the result of a defensive mistake in some way.
Harry Kane's fourth-minute opener came after Lovren tried to play offside from a throw-in, while the Croatian mistimed a header for Spurs' second.
And for Tottenham's fourth goal of the afternoon, Simon Mignolet came to punch the ball at a corner but missed it. Kane then found the back of the net for his second goal of the game.
One player that Liverpool do miss is Nathaniel Clyne, who brings pace and consistency at right-back but is currently out with a back injury.
James Milner took his place against Tottenham and while the 31-year-old is equally as consistent, he's not very fast - at all.
One moment in the opening 45 minutes encapsulated just how slow Milner is, when Son Heung-min absolutely roasted him before his goal.
In the video below, Milner has a 20-yard head start on Son but can do nothing as the South Korean roars past him. Check it out.
SON ROASTS MILNER
Naturally, football fans found Milner trying to keep with Son hilarious - he should really unhook that caravan of his! Here's how Twitter reacted.
