MILAN (AP) — Winning the derby ended up being the cherry on top of a special night for Inter Milan.

Holding off AC Milan 2-1 on Monday clinched for Inter the Serie A title that had been sign-posted for weeks, and earned a coveted second star on its jersey for winning a 20th Italian league title, breaking a tie with its fierce city rival.

“I told the guys, ‘We find ourselves in a situation that’s never happened before,’” Inter captain Lautaro Martínez said. “We needed to take advantage of this opportunity, because look around, the entire stadium is ours now.”

Not even the pouring rain could dampen the spirits of the Nerazzurri and their fans.

Francesco Acerbi and Marcus Thuram scored and, although Fikayo Tomori’s late goal for AC Milan threatened to delay the celebrations, Inter held on for the win that stretched its lead to an insurmountable 17 points over second-placed Milan, with five rounds remaining.
