Arsenal hosts Chelsea with clean sheets intact and favorite's tag at the Emirates

Arsenal arrives at the Emirates Stadium with the doors locked shut: two games, two wins and not a single goal conceded. Chelsea, on the other hand, has been winning in blowout fashion but also leaking goals, and that contrast in styles is the first big storyline of this Premier League clash.

The league numbers tell the story clearly: Arsenal has two wins from two matches, four goals scored and zero allowed, a rock solid defensive foundation that has the club sitting second in the table with six points. Chelsea, fourth with the same six points, has also won both of its matches, but with a more open scoreline, seven goals scored and five conceded. Looking at recent form (each side's last five matches, a different sample from the league record), Arsenal comes in with three wins, a draw and a loss, while Chelsea has racked up four wins and a draw, with no defeats in that stretch.

Zooming in on this season's Premier League trend home and away (a separate sample of just two matches per team), Arsenal is averaging 2 goals scored and 0 allowed per game, with 100% of its matches ending in clean sheets and its most productive stretch coming between minutes 46 and 60. Bukayo Saka stands out there with two goals, while Kai Havertz and Martin Ødegaard have one each. Chelsea, in that same sample, is averaging 3.5 goals scored and 2.5 allowed, with no clean sheets at all, and tends to strike early, in the first 15 minutes. Cole Palmer and João Pedro lead that production with two goals apiece, and Morgan Rogers has added one.

A history that leans heavily toward Arsenal

The head to head record between the two sides, with eight meetings, is overwhelmingly in the home team's favor: 5 wins for Arsenal, 3 draws and zero wins for Chelsea, with a goal difference of 16 to 7 in favor of the North London club.

Probable lineups

Arsenal's lineup, with medium reliability according to our projection, would likely feature David Raya between the posts and a back line of Cristhian Mosquera, Riccardo Calafiori, Gabriel Magalhães and Ben White. In midfield, Myles Lewis-Skelly, Christos Tzolis, Martin Ødegaard and Max Dowman would appear, with Kai Havertz leading the line up front.

On Chelsea's side, the projection carries low reliability. The defense would be built around Maxence Lacroix, Wesley Fofana, Levi Colwill and Josh Acheampong, while the midfield would feature Jorrel Hato, Roméo Lavia, Malo Gusto and Pedro Neto. Up top, the likely front three would be Cole Palmer, João Pedro and Morgan Rogers.

What the numbers say

Our model, based on this season's trends, marks Arsenal as the clear favorite, though it doesn't fully shut the door on Chelsea:

The expected goals figures from our model (an in house estimate, not an official statistic) come out to 2.02 for Arsenal and 0.95 for Chelsea, for a projected total of 2.97 goals in the match. The home side's edge is clear, but the 16% margin for Chelsea is a reminder that the visitors have been scoring in bunches, and a game with drama at both ends shouldn't be ruled out.

With Arsenal defending an unbeaten record at the back and Chelsea needing to prove it can compete on even terms away from home, the Emirates Stadium is set for a match that could be decided as much by solidity as by finishing.
