Barcelona signing Alex Song fired a parting shot at Arsenal and manager Arsene Wenger yesterday. Just days after Robin van Persie quit for Manchester United in search of silverware, the Cameroon midfielder, 24, became the latest Arsenal ace to leave.

Song said: "I'm so happy to be here because everyone knows Barcelona are the best team in the world. I'm feeling like a young boy.

"To be part of this team is something I wanted to achieve when I was young.

"I always tried to think 'I will play for Barcelona' and now I have the opportunity to be here and play with the best players in the world - Messi, Xavi, Iniesta, Fabregas."
