Where would Liverpool be right now without Mohamed Salah and Virgil van Dijk?
It's a question Kopites probably shouldn't want to know the answer to given how important their latest signings have been this season.
In terms of Salah, the 25-year-old has scored 42 goals in the Premier League and Champions League combined and proved an absolute steal at £36.9 million.
As for Van Dijk, the Dutchman arrived for double that amount in January but has brought an assuredness and calmness to the back four.
Dejan Lovren has even looked impressive alongside Van Dijk, which speaks volumes about the confidence he gives his teammates.
So what do Liverpool's latest signings think of each other? Well, last month Van Dijk explained how tough it is to play against Salah in training and that he always has to be at his best.
"Mo's that kind of player that you just need to be on your best," he said. "There are ways to stop him, but I'm not going to tell you because I don't want our opponents to think about it.
SALAH VS VAN DIJK
"When he is 100% and in the zone then he can beat anyone. Is he a goal machine in training? Well, he tries!
"But as a defender, we need to step up our game obviously and makes sure we are aware. It makes us better. That's what we want, that's what it's going to be like at a top club."
Sounds about right - but what about Salah's views on Van Dijk?
Salah and Lovren sat down for a chat in Liverpool's latest video on their YouTube channel and at 3:57, the Egyptian says: "Let's talk about Virg."
And the four words that then come out of his mouth just about sum up the kind of player Van Dijk has been since joining Liverpool: "The toughest guy ever."
Salah then hilariously explained that he had to Google Van Dijk when he signed for Liverpool because he had no idea how old he was.
"I Googled how old he is, I expected 35 or 36," the Egypt international continued, "but to be honest he's a great player. Great man.
"He never pays in the restaurant, but it's fine. He's a top guy. I'm very happy to see him around to enjoy the way he plays."
Clearly Salah and Van Dijk are both loving playing together and things could get even better if they manage to beat Real Madrid in the Champions League final this Saturday.
