【正文】 s my time to give back. 。m genuinely excited about what lies ahead. I39。 sacrifice, which made me realise my dreams. I owe everything to Victoria and the kids, who have given me the inspiration and support to play at the highest level for such a long period. I also want to thank Simon Fuller and his team for their continued support. I want to thank all my teammates, the great managers that I had the pleasure of learning from. I also want to thank the fans who have all supported me and given me the 13 strength to succeed. Nothing will ever pletely replace playing the game I love, however I feel like I39。t have achieved what I have done today without my family. I39。m thankful to PSG for giving me the opportunity to continue but I feel now is the right time to finish my career, playing at the highest level. If you had told me as a young boy I would have played for and won trophies with my boyhood club Manchester United, proudly captained and played for my country over one hundred times and lined up for some of the biggest clubs in the world, I would have told you it was a fantasy.
