He said: â€śSince leaving Chelsea, this will be my first time back in England since I left in September 2007.
â€śIâ€™ve not even been to my lovely house in London. Nothing. Iâ€™ve not even been shopping.
â€śSo, it will be emotional to go back to England. I will be in the stands at Old Trafford but I probably wonâ€™t even see anyone from Chelsea after the game.
â€śI will watch the people I love, the people who I have a great feeling for, but probably wonâ€™t speak to them. I still believe Chelsea are in a great position.
â€śThey are in the last 16 of the Champions League so anyone can win from the last 16. They are second in the Premier League. Chelsea was my team and it was my passion and it was not easy for me to leave them behind.
â€śWithout Chelsea, it is easy because I love it here. I could stay here for a long time, the passion will be there.
â€śBut I still see Chelsea from a long way away. I want them to succeed but it is not my team anymore. Bosingwa, Ivanovic, Anelka and Deco are not my players.
â€śMy focus is on United and I will be at the game on Sunday to watch them. Iâ€™ll do my preparations and after that I will have them watched by my scout.â€ť
