Victor Osimhen rescued Napoli a 1-1 home draw against Barcelona in the first leg of their Champions League last-16 tie in his first appearance for the Italian club since December.

Osimhen, who had served a ban in Napoli’s previous game after returning from Africa Cup of Nations duty for runners-up Nigeria, stole clear in the penalty area with 15 minutes remaining to fire home an equaliser.

Barcelona had taken a deserved lead on the hour-mark through Robert Lewandowski’s 93rd Champions League goal.

It was Napoli’s first game since they sacked head coach Walter Mazzarri after three months in charge and replaced him with Slovakian Francesco Calzona.

Porto winger Galeno’s stunning stoppage-time winner clinched his side a 1-0 win against Arsenal in the first leg of their tie.

Arsenal looked set to return to London all-square after a cagey tactical battle at Estadio do Dragao, but Brazilian Galeno crashed home a shot from outside the box in the fourth minute of added time.

The Gunners, bidding to reach the tournament’s last eight for the first time since 2010, created few chances, while Galeno struck a post with a close-range effort in the first half.

Kai Havertz had Arsenal’s best two chances late in the first half, firing off target from six yards before heading Bukayo Saka’s corner just wide.

The two sides will meet in the return leg at the Emirates Stadium on March 12.
