36' Berardi pushes over Kessie to hand Milan a free-kick in midfield. It's close enough for Calhanoglu to have a pop as he fires under the wall but it's nothing Consigli can't handle.
35' The corner comes out to Tonali whose thunderous shot from the edge of the box is blocked. So is Hernandez's effort. Now it's Sassolo's time to counter but Berardi has very few options.
34' Kessie intercepts Bourabia's pass and Milan go on the counter-attack. It doesn't work out first time so Milan keep possession and try again. Saelemaekers wins a corner for the visitors.
32' Hernandez shows intimidating pace to power towards Sassuolo's goal. Toljan does just enough to dispossess the Frenchman.
30' Chance for Sassuolo! Berardi fires a crossfield pass to Djuricic who reaches the box and finds Traore on the overlap. Traore cuts back to Berardi whose shot clatters off Romagnoli and out for a corner. Milan see the corner away as Calhanoglu is fouled by Berabia.
28' Sassuolo come back on the attack but they're not moving the ball around fast enough. Calabria's fluffed clearance almost puts him in trouble until Saelemaekers comes across to bail him out.
25' Sassuolo are building in confidence after their slow start. Berardi has another try from range, firing over this time, before the hosts win another corner off Calabria.
23' Berardi finds himself with some time on the edge of Milan's box and has a crack at goal. Donnarumma gets down low to his right to save it. It's a routine stop.
21' Sassuolo's German right-back Toljan gets up the other end and knocks the ball off Kessie for a corner to the hosts. Milan see it out fairly comfortably.
19' Hernandez's cross from the left is cleared by Toljan and Milan get their first corner of the game. Saelemakers blazes high and wide from outside the box from it.
17' Milan get a free-kick near the halfway line as Traore fouls Saelemaekers. It's floated towards Leao but Sassuolo get a free-kick as Berardi is blocked by Kessie.
15' Ferrari wins a free-kick for Sassuolo down the left flank as he's brought down by Diaz. Sassuolo are seeing plenty of the ball but are yet to create anything yet.
13' Sassuolo need to respond to this early flurry of Milan attacks. The visitors do not look like they are in the mood to mess around.
11' It's confirmed - Milan will not get a second goal just yet. Sassuolo breathe a sigh of relief.
9' Milan have the ball in the net again as Leao and Calhanoglu combine once more with Leao burning past Rogerio down the right to burst into the box. The Brazilian cuts back for Calhanoglu who slots home into the bottom left corner. The officials are taking a look for offside against Saelemaekers in the buildup...
7' Leao is being a nuisance for Sassuolo's backline. The Brazilian again gets caught offside from Calabria's throughball.
5' Milan are looking confident so far. Opta have confirmed that they took the lead after just six seconds. It's the fastest goal in Serie A history.
3' Donnarumma tries a direct pass from the back to send Leao through on goal. Milan's striker is offside though.
1' And we're underway!
The two sides are out on the pitch here in Reggio Emilia. Sassuolo are in their distinctive green and black home kit while Milan are wearing all-white.
Sassuolo have won just two home games this season, the lowest of any team in Serie A's current top seven, and haven't scored here since November. They're also winless in their last eight games against Milan. Will Milan show Sassuolo who's boss?
Sassuolo make six changes from their 1-1 draw away to Fiorentina last time out. Their midfield maestro Manuel Locatelli is suspended. There are three changes to the Milan side that drew 2-2 with Genoa midweek as Hernandez, Diaz and Saelemaekers come in.

Likewise, sixth-placed Sassuolo have come back to earth with a bump after a lightning start to the season. While the goals have dried up for Roberto de Zerbi's side, they're still hovering around the European places and would very much like to keep it that way.
Serie A leaders AC Milan will be looking to regain their early-season momentum as their title tilt has taken a dent through two successive draws. Stefano Pioli's Rossoneri are really missing their injured star striker Zlatan Ibrahimovic. The Swede's teammates will need to keep fulfilling their goalscoring responsibility in his absence.
