Portugal vs Croatia arrives in the World Cup round of 32 with Portugal carrying the edge. They have lost just one of 10 meetings in all competitions, and that record is backed by Opta simulations that give Portugal the stronger path through normal time.
The Opta supercomputer ran 25,000 pre-match simulations and gave Portugal a 54.5 percent chance of winning inside 90 minutes. Croatia were rated at 20.4 percent, while 25.1 percent of the simulations finished level after normal time.
Portugal’s unbeaten competitive run
The sharper detail for Portugal is the six-match competitive run. They are unbeaten across those meetings with Croatia, winning five and drawing one. That is the cleanest historical edge in the matchup, and it is why Portugal enter as the favoured side rather than the team trying to overturn the numbers.
For a knockout game, that split matters in practical terms: Portugal do not need to invent a new approach to justify their status. They already have the head-to-head record and the simulation data pointing the same way, which leaves Croatia trying to solve a pattern that has held up over multiple meetings.
Opta’s 25,000 simulations
Opta’s model does not predict a certainty. It turns the matchup into probability bands after 25,000 runs of the same pre-match setup, then assigns each side a share of the possible outcomes. In this case, Portugal were the most likely winners inside 90 minutes, Croatia were the least likely, and a draw occupied a meaningful chunk of the spread.
That is where the tension sits. Portugal’s strong historical record against Croatia contrasts with Croatia still having a 20.4 percent chance of winning in normal time. The numbers leave room for an upset, even if the wider forecast still leans Portugal’s way.
England and the last 16
The knockout stage has already shown how quickly a match can flip. England beat the Democratic Republic of the Congo 2-1 in Atlanta on Thursday, with Kane scoring twice late to turn a 1-0 deficit into a 2-1 win and send Thomas Tuchel’s side into the last 16. Brian Cipenga had put the Democratic Republic of the Congo ahead early on.
That result is the backdrop for Portugal and Croatia. Seven teams had already reached the last 16 with three of the six days of the round of 32 complete, so the margin for error is already shrinking. Whether Portugal turn their statistical edge into progression is the part this matchup still has to settle.
