Milan continued their unbeaten start to the Serie A season with a 1-1 draw against their rivals Inter Milan in an exciting "Derby della Madonnina" on Sunday, maintaining a seven-point lead over the defending champions. Hakan Çalhanoğlu, who moved from Milan to Inter in a free transfer this summer, made an immediate impact against his former club by winning and converting a penalty in the 11th minute. However, Inter's Stefan de Vrij headed the ball into his own net just six minutes later, equalizing the score for Milan. Milan's goalkeeper Ciprian Tătărușanu made a remarkable save from a penalty taken by Lautaro Martínez in a physically intense first half. Milan substitute Alexis Saelemaekers came close to scoring a stunning goal in the 90th minute, but his powerful shot hit the post. Milan remains in second place with 32 points on goal difference behind Napoli, while Inter, the defending champions, sits in third place with 25 points.
