Barcelona midfielder Cesc Fabregas has spoken of his desire to one day play for Arsenal again.The Spanish international left the Emirates Stadium in the summer after a protracted transfer saga involving the Gunners and the club where he first began his career.The 24-year-old eventually joined the European champions for an initial fee of €30 million, but says that leaving north London was a deeply emotional time for him."If I have to leave Barcelona, I will go back to Arsenal - I would like to," Fabregas told Sky Sports News. "I am not embarrassed to say that the day I left I could only say 'Thank you very much', I couldn't say more."I'm not embarrassed to say that I nearly cried. Arsene Wenger, I have never met someone that loyal. He is one of the best, I really believe that."
