Seven-time Formula One world champion driver Michael Schumacher announced on Thursday that he will retire from the sport at the end of the current season. Schumacher, 43, made his announcement at a press conference in Suzuka, Japan, in advance of the Japan Grand Prix. His final race will be in Brazil on the final weekend of November. This is the second time Schumacher has announced his retirement. He originally retired in 2006 before returning with Mercedes in 2010. Mercedes officials had announced last week that Schumacher would be replaced by Lewis Hamilton next season. However, there were reports Schumacher might move to Sauber. Instead, the German driver chose to retire. ''Basically, I've decided to retire at the end of the year,'' Schumacher said at the press conference. ''Although I was able and capable of competing with the best drivers that are around, at some point it's time to say goodbye and this time it might be forever.'' Schumacher began his career in 1991 and holds the record for number of championships, with seven, and for grand prix wins, with 91.
