Oct.4 (GMM) Michael Schumacher on Thursday announced he will return to retirement at the end of the season.

The news, announced by the seven time world champion at Suzuka ahead of the Japanese Grand Prix, follows Mercedes' decision to replace him for 2013 with Lewis Hamilton.

Schumacher, 43, had been linked with a move elsewhere, but with his voice creaking with emotion he said in Japan: "I still feel I am capable of competing against the best but the time sometimes comes to say goodbye and this time it might be forever."
