Angry Mikel Arteta slams Arsenal over two things they lacked in Champions League loss in Porto

Mikel Arteta insists Arsenal must do better if they’re to overturn Wednesday night’s defeat to Porto - after failing to manage a single shot on target.

The Arsenal boss was unhappy that his side had failed to stamp their authority on proceedings during their drab 1-0 loss in the Champions League last 16, first leg.

The Gunners were far from their free-flowing, attacking best in Portugal on Wednesday night, but looked set to return him with a goalless draw. However, a stunning 93rd minute effort from Brazilian forward Galeno handed the home side victory, and the lead ahead of the second leg in North London in three weeks time.

Speaking at full-time, the Arsenal boss couldn’t hide his frustrations with his side’s display and their inability to do more in the final third.

“We have to manage much better. We cannot win with the way we handled the ball on three occasions in deep areas. If you want to be in the quarter-finals you have to beat your opponent and this is what we will have to do at the Emirates now.

"We lacked threat. We lacked aggression, especially with the ball in the final third. We can do better."

Asked whether it had been down to Porto making things difficult or his side’s shortcomings, Arteta told TNT Sport: "I think it's a team that's very well-organised defensively and they break your rhythm all the time. There are certain things we will have to do much better, we know what to expect."

Arsenal midfielder Declan Rice questioned whether he and his team-mates had shown a bit of naivety late in the day, failing to keep possession deep into stoppage time, giving the ball away repeatedly before being brutally punished by Galeno.

He said: "When it's 0-0, you look up at the clock and it's 93 minutes gone, if you aren't
