Arsenal manager Mikel Arteta had plenty to reflect upon, after they went down 1-0 to a late Porto strike in the first leg of their Champions League Round of 16 tie at the Stadio do Dragao.

Arsenal were moments away from earning a draw from the first leg in Portugal on Wednesday, when Brazilian Galeno scored a screamer to give the hosts a narrow advantage at half-time in the tie.

After the game Arteta said:t “It’s tough to play here. They are really well organised and we have some problems, especially in the first half to attack much better.

“But when we had total control, dominance of the game and we looked to be more of a threat, play more in the final third, generate I think 10 or 12 corners, we didn’t make enough of that.

“And then the way we gave the ball away, especially in those deep areas in the Champions League, you pay the price and now it’s just half time. It’s clear what we have to do. Now, it’s more clear than before. You want to be in the quarter finals, you have to beat the opponent and, we’re going prepare that for our supporters to have a real go.”

The last time Arsenal faced Porto at this stage of the competition, back in 2010, they turned round a one-goal defeat from the first leg and triumphed 5-0 at home to progress, and it’s all to play for again when they welcome the Portuguese side to Emirates Stadium on March 12.
