Alex Iwobi on Olivier Giroud's stunning strike against Crystal Palace

Alex Iwobi has revealed that the Arsenal squad was left open-mouthed by Olivier Giroud's superb goal against Crystal Palace on New Year's Day.

The Frenchman's spectacular back-heeled volley was the first goal in Arsenal's 2-0 triumph over the Eagles on Saturday.

Giroud met Alexis Sanchez's cross by volleying the ball over his own head and in off the crossbar.

The 20-year-old Nigerian midfielder netted the other goal at the Emirates and Iwobi admitted: "A lot of people were coming into the dressing room with their mouths open.

"They couldn't believe it. They were all congratulating him but it was only half-time. At the end of the game we could say well done Ollie.

"It's rare. We have some special players and you do see the odd crazy thing but nothing like that has ever happened in training.

"Ollie scored a special goal. I have never seen a better goal than that live. It was amazing for me as well to get another goal in the Premier League."

Iwobi has now made 23 appearances for the Gunners this season, in all competitions, more than he made during the entire 2015/16 season.

And he is delighted to be wearing the Arsenal shirt more times this campaign: "This time last year I was just playing in the cup games and happy to be there.

"To be starting almost every week is just amazing progress for me. I'm still young, still learning and there is still a long way to go.

"Number 10 is where I have grown up playing and where I enjoy playing the most but wherever I am put on the pitch, I will do my best and whenever I get told to play any position I give 100 per-cent.

"There are a lot of players who can play number 10, and a lot of ball players in the team. Every day in training I am always learning and trying to add it to my game."
