Real Madrid's defence has faced more than a few world-class opponents in this season's Champions League but none compare to Mohamed Salah based on current form.
None compare to Liverpool's front three as a whole, in fact, with Salah, Roberto Firmino and Sadio Mane arguably the most dangerous attacking trident in the world right now.
Forty goals the Reds have scored in Europe this season, with the aforementioned trio accounting for three-quarters (30) of those.
Salah, Firmino and Mane really have been on fire, so if Real are going to have to be on top form defensively to have any hope of winning Saturday's final.
And that all starts with captain Sergio Ramos, who is a serial winner and must use all his experience to keep things tight at the back.
He was asked about the threat of Salah in his pre-match press conference on Friday evening and responded by giving his honest opinion on the Egyptian.
Ramos thinks Salah is a great player but doesn't agree with the comparisons to Cristiano Ronaldo and Lionel Messi, who he describes as "from another orbit".
RAMOS: SALAH IS FANTASTIC
What's more is the Spaniard believes Salah must continue producing crazy numbers over the next few years to justify being compared to Ronaldo and Messi, which is absolutely true.
"For me to compare players with Cristiano and Messi... these guys are in another orbit," he said. "There are players who are 'in vogue' and others who aren't, but this depends on the player himself.
"There are players who come and then drop off and then others who are there to stay. It's clear that Salah's a fantastic player.
"Everyone has their opinion and you have to respect that a lot of people want to compare him with these kind of players. For me he's a brilliant player and he's shown it, above all this year.
"He's got a great chance to prove himself and stay at the top over the next few years as Cristiano and Messi have done. In that sense I wish him all the best - from the day after tomorrow that is."
Very well said, Sergio. Football fans wholly agree with Ramos and have been praising the Spain international for speaking so honestly about Salah.
