Stellar career of superstar Frankel
- From the section Horse Racing
BBC Sport looks back on the career of horse racing superstar Frankel.
The Sir Henry Cecil-trained colt is unbeaten in 13 races and has been the highest-rated racehorse in the world since May 2011.
Frankel is expected to race for the final time before retirement - and a very lucrative stud career - in the Champions Stakes at Ascot on Saturday, provided conditions in Berkshire are deemed safe for the four-year-old.
