Former Arsenal hero Paul Merson was impressed with the way Yaya Sanogo scored, but admitted he was disappointed he didn't go on to double his tally.
The French under-21 striker scored after only 73 seconds against Borussia Dortmund, erasing all the talk about his goal drought since joining the club.
Merson told SkySports: "It was a good finish. He's not played since August, and it was good hold up play. (The offside was) bit of a home decision, but he has still got to put it away."
Later in the first half, Sanogo had another chance where he was through on goal, but stuttered and then tried to play in Santi Cazorla, before the ball was cut out.
Merson admitted to being underwhelmed that Sanogo did not go on and try to net his second of the game.
He added: "He's got to go (on), hes quick enough. He's got to pull the trigger.
"He's not got confidence, I'm not sure why - he's just scored. He's just got to put his head down and go, swing it."
It's doubtful Sanogo will be too picky, nor his manager Arsene Wenger. It was his first strike since joining the club in July 2013, and will make him feel far more relaxed at the club.
The real disappointment to his evening was his late injury, withdrawn after 80 minutes with a hamstring injury, and may have to wait a little while until his next opportunity.
