When will Jurgen Klopp do something about Liverpool's defence?
The Reds boss has, rather bizarrely, claimed that neither signing players nor working on set pieces in training will help the situation.
It's no exaggeration to say that casting aside Mamadou Sakho, who has just made his move to Crystal Palace permanent, was one of the German's more questionable decisions in his two years at Anfield.
Liverpool are now left with Dejan Lovren at centre-back and Alberto Moreno on the left.
So far this season, it's been a recipe for disaster, as they've dropped needless points against Watford and Burnley and received a 5-0 thrashing at the hands of Manchester City.
Unfortunately, until they sort out their problems at the back, it's hard to envisage them seriously challenging for either the Premier League or the Champions League. It's a crying shame too, considering their brilliance at the other end of the pitch.
It will certainly be interesting to see how far they get in Europe. Of course, the club have a special affinity with the competition given their illustrious history, though they're not among the favourites to win it this year.
After drawing 2-2 with Sevilla in their first outing, they will face Spartak Moscow on Tuesday night.
That could be very good news indeed. Bear with us here, because we're not sure if this is even possible, but it seems the Russians may have an even worse defence than Liverpool. Yes, really.
What is this?
In a clip - brought to our attention by the Mirror - of Spartak's recent game against Anzhi Makhachkala, they look to have left just one defender at the back, despite the game being evenly poised at 1-1.
Check it out below - skip to 3:49 for the moment we're talking about:
Absolutely shocking! Sadio Mane has been missing out in the Premier League through suspension following his challenge on City goalkeeper Ederson, but he'll be free to play against this woeful lot in midweek. It doesn't bode well.
If both sides defend as we know they can - which isn't a compliment - there should definitely be goals in this one.
