Porto snatched a shock last-gasp 1-0 victory over Arsenal as Galeno netted a sublime effort deep in stoppage time in their Champions League Round-of-16 tie on Wednesday.

A drab clash was deadlocked until the fifth minute of added time when the Brazilian winger curled an unstoppable effort past David Raya to send the Estadio Do Dragao crowd wild.

Arsenal, who had scored 21 goals in their last five Premier League games, were strangely subdued in attack and failed to register an effort on target throughout a cagey contest.

They defended solidly enough but may live to regret their lack of urgency as Galeno gave Porto the edge ahead of the second leg in London on March 12.

Arsenal are seeking to reach the quarter finals for the first time since 2010 with their last seven Champions League campaigns all ending in the last 16.

“We had to manage the game better when you can’t win,” Arsenal manager Mikel Arteta said. “We lacked threat and aggression in the final third and we need to tweak a few things. We can do better.

Reassuringly for Arsenal, Porto have a terrible record away against English clubs and have never scored at Arsenal, conceding 11 in three visits. But the 30-time Portuguese champions will travel with hope.

Dour draw

Napoli fought back to hold visitors Barcelona to a dour 1-1 draw in their first-leg game as Victor Osimhen cancelled out Robert Lewandowski’s
opener.

Last year’s Spanish and Italian champions, both struggling this season, played out a poor match in which both sides were toothless and lacking attacking flair.

Barca were playing their first Champions League knockout match for three years while Napoli were led by new coach Francesco Calzona with their Serie A title defence in tatters as they languish ninth in the domestic standings. Napoli were frustrated by Barca’s high pressing, missing simple passes and gifting the ball to the visitors who also looked short of ideas in possession.

Poland striker Lewandowski put Barca ahead in the 60th minute after receiving a pass from Pedri just inside the box and he made space to unleash a bullet strike into the bottom corner of the net.

That woke Napoli up and Nigerian Osimhen equalised 15 minutes later with a fine swivelling strike from inside the box to leave the tie evenly poised ahead of the return leg in Spain on March 12.

“It is not a good result for the return leg,” Barca manager Xavi Hernandez told Movistar Plus.

“We were better in all aspects of the game, we had to control and we struggled.”
