He's got no love for either man ... so we asked Matt Barnes who he'd rather fight, Derek Fisher or Colin Kaepernick?
His answer -- "I'll f*** both of 'em up."
Boom!
As we previously reported, Barnes has had animosity toward the 49ers QB for years -- stemming from a situation where Matt felt "disrespected" by Colin. Clearly, there's still strong feelings.
BTW, we also asked Matt if OKC Thunder star Steven Adams should get a pass for calling the Warriors "quick little monkeys" Monday in his post-game interview.
