Jurgen Klopp recently indicated that Liverpool's summer of spending was over but, following his side's 2-1 defeat to Roma on Tuesday, it would appear that's no longer the case.
Sadio Mane, Georginio Wijnaldum, Loris Karius and Joel Matip - among others - have all arrived on Merseyside over the past few months yet that might not be enough after recent injury setbacks.
Mamadou Sakho, Joe Gomez and Lucas Leiva are all out injured whilst the much-maligned Alberto Moreno limped off in St Louis with a dead leg.

Klopp now faces something of a defensive crisis at left-back, even if he does opt to field the versatile James Milner in the above's absence.
And that seems to have forced the former Borussia Dortmund boss back into the transfer market ahead of the new Premier League season.

According to the Daily Mail, Liverpool have earmarked FC Koln full-back Jonas Hector as a potential target - let alone an upgrade on Moreno.
The £20 million-rated Germany international, who took part at Euro 2016, is a consistent performer in the Bundesliga and would add defensive steel and pace going forward.
Indeed, even if Moreno hadn't hobbled off against Roma, Klopp would be wise to buy a replacement.
Following his side's defeat, the eccentric German said: "Is the activity all over? I have no idea. I don’t think so. We will see what happens.
"What you saw (in St Louis against Roma) was an example of how you can’t defend; leaving spaces so big you could have cut grass in between.
"Their strikers did okay but we were too wide, too deep and too far from each other so each pass they played was a chance.
"Gomez, Sakho and Lucas are all injured so, of course, we haven't got enough centre-backs at the moment. There have been too many games with not enough centre-backs."
So out of favour is Moreno at Anfield that, following a season where he was at fault for a number of important goals, fans are calling for the Spaniard to be sold.
Whilst a threat going forward, misplaced passes and poor judgement continue to plague his defensive duties.
A particular example of his deficiencies at the back came against Sevilla in the Europa League final, when his double error led to an equaliser for the La Liga outfit.
Signing the aforementioned Hector would hopefully eradicate such errors and conclude what has been a promising transfer window for Liverpool.
