Inter Milan secured a 2-1 home win over Fiorentina on Monday, with Marko Arnautovic's second-half header keeping them within striking distance of Serie A leaders Napoli.

The win was a blessing for second-placed Inter, who now have 54 points, closing the gap on Napoli to just one point.

Inter hosted Fiorentina just four days after their last Serie A clash - the second shortest interval in league history. Fiorentina ran out 3-0 winners in the match, which was abandoned in the 17th minute on 1 December after Fiorentina midfielder Edoardo Bove suffered a cardiac arrest and collapsed on the pitch.

Inter controlled much of the game, pushing forward early and creating several chances, with Carlos Augusto and Lautaro Martínez both hitting the woodwork within minutes of each other.

While Inter's attacking prowess was on full display, their momentum was briefly halted when striker Marcus Thuram, who had been limping for several minutes, was forced off and replaced by Arnautovic.

Despite dominating possession, Inter could only break the deadlock through an own goal from Fiorentina's Marin Pongracic, who headed the ball into his own net from a corner in the 28th minute.

The visitors equalised a minute before the break when Rolando Mandragora converted from the penalty spot after Matteo Darmian's cross.

Seven minutes after the restart, Arnautovic put Inter back in front with a close-range finish from Augusto's cross to secure all three points.

Augusto admitted that the win was important following the poor performance in the previous match at Fiorentina."There was anger because in Florence we weren't ourselves, it's normal to be criticised, today we showed our strength again," he said.
