Inter Milan slipped to a 2-1 home defeat as Udinese came from behind to take the points at the San Siro.

Denzel Dumfries fired Inter into a 17th-minute lead, but then conceded the penalty from which Keinan Davis brought Udinese level 12 minutes later.

Arthur Atta completed the turnaround five minutes before half-time and that is how it stayed as Inter saw a 56th-minute equaliser from Federico Dimarco ruled out for offside after VAR intervened.

Inter were looking to build on their 5-0 thrashing of Torino in their Serie A opener on Monday night and took charge when Dumfries turned in from close range after neat work from Marcus Thuram to set up an easy finish.

But Dumfries then handled in his own box with the penalty given after a VAR check, and Davis found the bottom corner to bring Udinese level.

Davis then turned provider as the visitors hit Inter on the break five minutes before half-time, with Atta beating Yann Sommer with a shot from outside the area.

Dimarco looked as though he had scored a fine equaliser with a neat finish 11 minutes into the second half, but it was ruled out after a review with Thuram offside as he nodded the ball down for Dimarco.

Davis almost killed the game off with a neat bit of skill himself, only to fire wide, but Inter could not make the most of the let-off as Piotr Zielinski was denied in stoppage time.
