10 Active Boxers Who Could End Their Career Unbeaten

While Rigondeaux struggles for opponents because of how he fights, Gennady Golovkin finds it difficult to attract significant foes because he punches like a mule and has never been knocked down as a amateur or professional.

Ahead of his meeting with Dominic Wade on April 23, the Kazakh has recorded 21 successive stoppages but he and promoters K2 are eager to secure the kind of showdowns that will ensure that he will go down in history as one of the best ever.

The 33-year-old has Saul Alvarez in his sights and that bout is regarded as the biggest fight that can be made in 2016 but if he cannot tie down the Mexican, Golovkin can look to unify the middleweight division which has been his aim for a while.

Regardless of his next moves however, it is difficult to see how Golovkin will ever be beaten. Too many potential opponents won't step into the ring with the 2004 Olympic gold medallist unless he competes at their designated weight but even if that occurs, it probably won't be enough to soften his punches or weaken his physicality.

Golovkin has the mindset where he will step into the ring with anyone but unfortunately for him and boxing in general, others aren't so reciprocating.
