Arsenal manager Mikel Arteta bemoaned his team's lack of cutting edge as Galeno's sublime stoppage-time goal earned Porto a 1-0 win in the first leg of their Champions League last-16 tie on Wednesday.Appearing in a first knockout match in Europe's premier club competition for seven years, Arsenal struggled to break down an organised Porto defence before Galeno's stroke of brilliance in the 94th minute.The defeat ended Arsenal's eight-game unbeaten run against Portuguese opposition and the Gunners with plenty of work to do in the return leg in London on March 12."We lacked threat.
We lacked aggression, especially when we had the ball in the final third," Arteta told TNT Sports. "So we will tweak a few things to attack better.
We can do better."Arsenal last made it to the Champions League quarter-finals in 2010, when they beat Porto in the last 16, but it is the Portuguese club who now have the upper hand. "I think it's a team that's very well-organised defensively and they break your rhythm all the time," said Arteta."We want to be in the quarter-finals, you have to beat your opponent and this is what we have to do at the Emirates."Arsenal failed to register a single shot on target as their recent goal spree came to a shuddering halt."When it's 0-0, you look up at the clock and it's 93 minutes gone, if you aren't going to win the game then don't lose it," said Arsenal midfielder Declan Rice."It's a real kick in the teeth because we've conceded late but we know what to do.
We're not going to let our heads drop." Wednesday: Last 16, first legs In Porto, Portugal FC Porto (POR) 1 (Galeno 90+4) Arsenal (ENG) 0 In Naples, Italy Napoli (ITA) 1 (Osimhen 75) Barcelona (ESP) 1 (Lewandowski 60) Tuesday: In Milan Inter Milan
