Inter Favorites in Rotterdam Despite Sitting 20th: What's Behind the 53%

The number that stands out: Inter are 20th in the Champions League table, with 3 points from 3 games. Yet the market prices them at 53% to win in Rotterdam. Feyenoord, 26th and also on 3 points, sit at 25%.

A quick primer if you're new to prediction markets: the price of a "Yes" share reads as the market's implied probability. Here, "Yes" on Inter is 53% and "No" is 47%. On Feyenoord, "Yes" is 25% and "No" is 75%. Trading volume over the last 24 hours is $3,938 on the Inter market and $1,467 on the hosts' market.

Why the market trusts Inter

The table alone doesn't explain the price: both sides have the same record, 1 win and 2 defeats from 3 games, in a 36-team league phase. The difference is in the goals. Inter have scored 5 and conceded 6. Feyenoord have scored 4 and conceded 8. Inter's goal difference is better: -1 against -4, a 3-goal gap.

Then there's form, across the last 5 games in league and cup.

• Inter: 4 wins and 1 defeat, 9 goals scored and 5 conceded. The defeat is the 1-3 against Milan, but before that came a 2-0 win at Venezia, 2-1 over Fiorentina, 1-0 against Shakhtar in the Champions League and 3-1 at Bologna.
• Feyenoord: 2 wins, 2 draws and 1 defeat, 9 goals scored and 8 conceded. Two 1-1 draws in a row in the Eredivisie, against Fortuna Sittard and PSV. In the Champions League, a 0-1 loss to Betis and a 3-2 win over Como.

The stat that matters: Feyenoord have conceded 8 goals in 5 games, more than 1 per match. The 4-3 against Telstar is a case in point.

Head-to-head

The data shows two meetings, both won by Inter: 2-0 at Feyenoord and 2-1 at San Siro, 5 goals in total. A tiny sample, but consistent with the price.

Where the market could be wrong

Inter aren't arriving at full strength. Bastoni (red card), Jones, Luis Henrique and L. Martinez (all with a thigh problem) and Stones (muscle problem) are out. Pavard (thigh) and Provedel (illness) are doubtful. With 5 confirmed absences and 2 doubts, 53% is hardly a safe bet.

Feyenoord have their own problems too: 3 confirmed absences and 4 doubts. Beelen (broken leg), Bos and Nieuwkoop (knee problems) are out. Nelson (muscle problem), Smal (ankle), St. Juste (leg) and van Persie (a knock) are doubtful. That weighs on a side that has already conceded 8 goals in 3 Champions League games.

The picture, then: the market rewards Inter's form and goal difference, and it doesn't erase Saturday's defeat to Milan. Feyenoord's 25% is limited confidence, but not zero.

What to watch

Between now and kickoff, keep an eye on the fitness of Pavard and Provedel on the Inter side, and on Feyenoord's four doubts. Then the volumes. Today the Inter market has traded $3,938: see whether it grows.
