Sing a song in public, make a video of it, impress Thierry Henry and win a free Arsenal shirt. The Arsenal legend, in a video of his own, has called on the Gooners to put their vocal chords to full use by singing a terrace anthem.

Puma, Arsenal's new kit sponsors, will grant the best/loudest three videos a free shirt.

The sports manufacturing company have been putting the Arsenal brand out feverishly after inking the £30 million a year deal with the club, with fans in India also given a rare treat recently when they got to interact with "Invincible" Freddie Ljungberg.

Meanwhile, one of Arsenal's summer signings – David Ospina has spoken about making his club debut in the 2-1 defeat to Southampton in the Capital One Cup third round match on Tuesday.

"I'm really happy to make my debut and play my first game with Arsenal," the 26-year-old Ospina told the club's official website. "Unfortunately we didn't win and the result went against us but I just want to keep working. I'm really tranquil because I did my best.

"The second [Southampton goal] was superb and [Nathaniel] Clyne is a really skilful player. There were a lot of people in the box and when I saw the ball, it moved and I didn't have time to react.

"We would have liked to have kept going in the cup. It was one of our aims and the result was not very good for us. Everyone was sad afterwards because we want to win more titles for Arsenal."

Ospina, signed for around £3 million from Nice in the summer transfer window, was injured for the first few games of the season, and has then had to sit on the bench with Wojciech Szczesny showing good early-season form.

The Colombia international goalkeeper will hope for more opportunities in an Arsenal shirt as the season goes by, with the new signing seen as pretty good competition for Szczesny, who does have the habit of becoming a little complacent and over-confident.

"I felt really happy when I went onto the pitch because people were supporting me a lot," Ospina added. "I'm learning all the time, and I will keep working. The style in England is different because they play really quickly and with a lot of aerial balls.

"Little by little, I'm learning English too. I'm taking classes and some of my teammates speak French. There is a mix of languages spoken so little by little, I understand them better."
