Preview
Paris Saint Germain host Barcelona in the UEFA Champions League on Tuesday, October 20, with both sides arriving on winning runs and level on points in the table. The model gives the contest a narrow shape at the top of its outcome order, while its expected-goals figures point towards a markedly different balance between the teams.
What the model expects
These probabilities are estimates. The model's outcomes from likeliest down are a Paris Saint Germain win (40.7%), then a Barcelona win (39.7%), then a draw (19.6%).
The goals projection leans towards an open game: over 2.5 goals at 71%, compared with under 2.5 goals at 29%. Yet the model has 60.4% for at least one side failing to score, against 39.6% for both teams to find the net. Those figures sit alongside a sharp split in expected goals, with Paris Saint Germain at 3.2 and Barcelona at 0.5.
The most likely exact score is 3-0 at 12.5%, followed by 2-0 at 12.2% and 4-0 at 9.9%. Each of those leading scorelines has Barcelona shut out, a clear feature of the model's forecast, though not a promise of how the match will unfold.
Form and standings
Paris Saint Germain have WWDDW across their last 5 games, a sequence that amounts to 3 wins and 2 draws. They have 17 goals scored and 9 conceded, and their latest outing was a 4-2 away win against Manchester City on October 14. The current run is 2 wins in a row.
