Arsenal lost to Porto 1-0 in the first leg of their Champions League last-16 tie on Wednesday night, but more than Galeno’s late stunner, it’s the Gunners’ offensive flaws that should worry Mikel Arteta and the Londoners’ fanbase.For only the second time on record (since 2003-04), Arsenal did not have a shot on target in a UCL game, previously failing in such a way at Barcelona in the last-16 in March 2011.🚨🚨| GOAL: WHAT A GOAL BY GALENO!!!Porto 1-0 Arsenal pic.twitter.com/YzRwqSQZID— CentreGoals. (@centregoals) February 21, 2024 Arteta’s side dominated possession but failed to have a single shot on target, with Saliba and Havertz heading wide from corners.Unlike them, Galeno took a few touches to set himself before curling a superb finish into the net past David Raya. The very same player should have put them in front even before the break, but Galeno hit a shot off the post and somehow put the rebound wide.Arsenal failed to record a shot on target in the #UCL for the first time since March 2011 ❌#BBCFootball #PORARS pic.twitter.com/SaHOibquEX— Match of the Day (@BBCMOTD) February 21, 2024 The second leg will take place at Emirates Stadium on 12 March, when Arsenal will aim to reach the quarter-finals for the first time since 2009-10.UEFA CHAMPIONS LEAGUE1/8 finalsTuesdayCopenhagen – Man.City 1-3 (1-2)/Mattsson 34 – De Bruyne 10, Silva 45+1, Foden 90+3/RB Leipzig – Real Madrid 0-1 (0-0)/Diaz 49/WednesdayPSG – Sociedad 2-0 (0-0)/Mbappe 58, Barcola 71/Lazio – Bayern 1-0 (0-0)/Immobile 69 pen/Tuesday the 20thInter – Atletico Madrid 1-0 (0-0)/Arnautovic 79/PSV – Borussia Dortmund 1-1 (0-1)/De Jong 56 pen – Malen 24/Wednesday the 21stPorto – Arsenal 1-0 (0-0)/Galeno 90+4/Napoli – Barcelona 1-0 (0-0)/Osimhen 75 – Lewandowski 60/
