There are only two differences in the Liverpool lineups that beat Spurs 2-1 home and away this season.
Naby Keita and Joe Gomez started the September tilt at Wembley Stadium, while Jordan Henderson and Joel Matip started at Anfield.

Spurs on the other hand played a back four at Wembley with three center backs in the reverse fixture, wing backs Danny Rose and Kieran Trippier pushed up high and wide.
Might we see the latter again in Madrid? One of those pieces begins this examination of the three (plus one) factors in Saturday’s Champions League Final.
Kieran Trippier versus Sadio Mane
Mane scored 22 goals this season, but failed to manage one against Spurs whether Trippier was lined up at right back or as more of a right wing back.
All-in-all, the dangerous-crossing Trippier is a better defender than his reputation suggests, but Mane is about as explosive an attacking talent as there is in England.
This battle may be the one that settles the tie.
Roberto Firmino versus Toby Alderweireld
Sure, this also could read Firmino v. Spurs’ defense, but “Bobby’s” two goals against Spurs this season were his first in six matches against the Reds.
Like Harry Kane for Spurs, Firmino is coming off an injury. While still quite good, the Brazilian center forward’s production and effectiveness have both dipped this season.
Perhaps it’s absurd to expect him to be a wrecking ball in consecutive Champions League seasons, but his dip in that competition was especially significant. Firmino arguably was the number one reason Liverpool ran through its forgiving slate last season, scoring 10 goals with 7 assists and drawing a penalty. This year, it’s just four goals with a helper.
Alderweireld, meanwhile, has been fine but not spectacular for Spurs. The big Belgian will hope Firmino is less than 100 percent.
Jurgen Klopp versus himself
There are few men in the world with the self-confidence of Jurgen Klopp, but the Reds’ boss enters his latest final holding the proverbial clipboard for the unabashed favorites.
When a man has lost his last three European finals, there’s reason to question how he may try to out-fox himself in the role of favorite. It’s also worth noting that the virtue of getting to a fourth European final says a lot about a managerial skill set.
Where Spurs boss Mauricio Pochettino is very much playing with house money, Klopp has yet to lift a piece of silverware as Liverpool boss. Perception of him is unlikely to change too much with a loss, but a win would have him an Anfield all-timer.
The stage can do wild things to a man, even when that man has spent plenty of time on that stage.
BONUS: Harry Kane versus his ankle
Yeah, this is cheating, but the Englishman’s fitness is the X-factor of the UCL Final. Virgil Van Dijk has the goods to deal with a fully fit Kane, but if he’s simply tasked with managing a half-ready decoy? Well, that’s big stuff.
Still, Kane’s 1-4-4 record against Spurs doesn’t have a ton to do with his scoring record, as he’s managed five goals and two assists in those matches. If he’s ready to go, Spurs obviously have a much better chance at glory.
