Gennady Golovkin wants a 3rd crack at Canelo Alvarez -- telling TMZ Sports the plan is to start negotiating the trilogy fight right after he beats up Steve Rolls next weekend.
GGG and Canelo fought to a draw when they first battled back in 2017 -- and when they ran it back in Sept. 2018, Canelo got the victory in a controversial decision.
Those fights were clearly the BIGGEST of Gennady's career in terms of exposure and paychecks -- so, it's no shock Gennady is ready for Part 3.
