Arsenal have complained to UEFA after manager Arsene Wenger revealed an object - believed to be a bottle - was thrown at him after the final whistle in their goalless draw with Besiktas in the Champions League play-off first leg.

Wenger branded Aaron Ramsey's late sending off "unbelievable", and the Frenchman was targeted by the Besiktas supporters as he made his way to the tunnel at the end of the match.

"As I left the pitch a bottle or ­something was thrown at me," Wenger said. "I reported the incident to UEFA."

Wenger was left frustrated with the performance of referee Milorad Mazic. Ramsey, already on a yellow card, pulled back Oguzhan Ozyakup's shirt in the dying minutes at the Ataturk Olympic Stadium and was subsequently shown the first red card of his club career.

The midfielder will now miss next week's return leg at the Emirates Stadium.

"Both yellow cards for Aaron Ramsey are unbelievable. When you see the fouls they have made today it's not serious. Just not serious," Wenger told ITV.

Besiktas forward Demba Ba proved a constant threat for the home side as the former Chelsea striker went close on numerous occasions, while substitute Alex Oxlade-Chamberlain saw a late effort tipped on to the post.

Wenger conceded it was a frantic game and both teams wasted chances to take a lead to north London. However, the Frenchman believes his side are capable of doing the job at home in order to secure their place in the group-stage draw.

He added: "It was a difficult game played at a frenetic pace from the first minute to the last. We could have won it but they had chances as well, in the first half alone. In the end we didn't lose and hopefully we will make it at home.

Despite seeing Ramsey red-carded and Mikel Arteta walk off the pitch with a suspected ankle injury, Wenger took solace in a pleasing performance from summer signing Calum Chambers.

Wenger said: "I think he was once again very good tonight and very convincing in his performance. He coped with the pressure, won the challenges and played on a pitch that was not easy. He did very well."
