Porto face the Clássico without Froholdt, and miss Rodrigo Mora far more

The Dane's absence costs less than a point at the Dragão. The player Porto sold to Roma this summer would be worth four in the same part of the pitch.

Victor Froholdt is not on the teamsheet for the Clássico. Forty starts in forty-eight matches since he arrived last summer, a settled place in midfield, and an absence on Sunday night at the Dragão.

We priced it: eight tenths of a point of win probability. Not much, in a match our model gives Porto at 38% against 36. And far less than another absentee would be worth — an absentee who is not coming back, because he plays in Rome.

What Froholdt would have changed

Replaying the match with Froholdt in place of In-beom Hwang — the midfielder occupying his slot in the announced eleven — lifts Porto from 37.7% to 38.6%.

The gap between the first two lines is worth pausing on. The team model, which reads neither line-ups nor absences, gives Benfica 29.3%. The one that reads the announced elevens raises them to 36.4%. Seven points: that is the price of Porto's absentees, and the first model cannot see it.

Line-ups as announced before kick-off. The highlighted player is the one filling the vacant position.

The other absentee

There are absences a manager works around, and absences a stadium does not forget.

Rodrigo Mora left FC Porto for Roma on 19 August. Academy-raised, thrown into the first team at seventeen, fifty-seven matches in blue and white. The Dragão stands had made him their own business long before the market took an interest.

The ending looked less like a farewell than a slow fading out: eight starts in eleven matches in late 2025, then five in eleven in the first quarter of 2026. Francesco Farioli was easing him out of his eleven.

Our model never followed him down. It measures what a player produces per ninety minutes, adjusted for the quality of his team-mates and his opponents. Fewer minutes does not make a worse player. It makes fewer minutes.

+4.2points of win probability Rodrigo Mora would bring Porto on Sunday, in the slot Froholdt leaves empty

Put another way: the player Porto miss on Sunday is worth less than a point. The one they sold would be worth four more, in exactly the same part of the pitch.

The calculation only holds where it means something. Mora is a central attacking midfielder: we do not drop him in at centre-forward or at full-back, where measuring him against André Silva or Francisco Moura would say nothing at all. That leaves the two midfield slots he could genuinely occupy: the one Froholdt vacates, where he is worth +4.24 points, and Pablo Rosario's, where he is worth +3.36.

A Clássico Benfica approach better than it looks

Porto remain favourites at the Dragão, but only just: 38% against 36, with a quarter of draws. And most of that margin comes from the ground, not the squad.

Benfica arrive close to full strength. Porto have seven players in the treatment room, including Zaidu Sanusi, Gabriel Mec and Vasco Sousa, and line up without the midfielder they have picked for a year.

One point of probability does not decide a Clássico. But when two sides are less than two points apart, a point is worth vastly more than at the Vélodrome or the Etihad, where the favourites play above sixty.

And on Sunday night, somewhere between the twentieth and the thirtieth minute, when the Portuguese midfield is struggling to move the ball forward, there will be a few thousand people in the Dragão thinking about a nineteen-year-old who now plays in Italy.

Our model says they are right by four points.

Is PSG the Champions League favourite? Our two models rank it 1st and 10th

Our two models each replayed the 2026-2027 Champions League 50,000 times from the same 18 matches already played, and their rankings correlate at 0.944. On PSG, one gives a 24.5% title chance, the other 2.2%. The whole gap comes down to one question of method: should a squad be judged by its league's average?

João Pedro: one certain fixture, and a date that can slip

The injury feed declares a return on 17 October, the very day of Everton – Chelsea. The absence therefore covers only one fixture for certain, where it costs 1.72 points of win probability. If the date slips, it is a different fixture, and a different figure.
