Matt Barnes clearly doesn't forget any of his feuds -- that includes his rivalry with former teammate Derek Fisher and his beef with 49ers quarterback Colin Kaepernick.

The Grizzlies player has had a longstanding feud with Fisher ever since the former Knicks coach began a romantic relationship with his ex-wife, "Basketball Wives: L.A." star Gloria Govan.

As for Kaepernick, Barnes called him a "hoe" on Twitter back in May 2015 and apparently has had issues toward him for a long time because he felt disrespected by him.

So which of his enemies does Barnes believe he can take in a fight?

"I'll f--k both 'em both up, no question," Barnes told TMZ Sports. "If I had to, it would go down."

Though Barnes has repeatedly said he wants to get into a second physical altercation with Fisher, he was a little more measured this time around, saying he wouldn't want to fight either one of them, but could handle himself it ever happened.

At least Barnes won't have to worry about Kaepernick stealing one of his past girlfriends as the 49ers quarterback is in a relationship with Nessa, a New York City-based DJ and radio personality.

Barnes and Fisher already got into a fight back in October at Govan's house. Upon hearing that his former teammate was attending a party hosted by his ex-wife and was romantically linked to her, an incensed Barnes drove over to Govan's house and got into a physical altercation with him.

Though Govan and Fisher, who was fired as Knicks head coach back in February, were first keeping their relationship private, they came out in the public with it back in March.

Barnes, who recently posted a meme knocking Fisher after the D'Angelo Russell-Nick Young incident involving "Swaggy P's" fiancée Iggy Azalea, was very open about wanting to fight Fisher again in the past, but it seems he may be getting past it.

"I know I got to keep my mouth shut because then he'll run and tell," Barnes said about Fisher in January during the lead up to a Grizzlies-Knicks game via The New York Daily News prior to Fisher's firing. "So we're focused on playing that team [the Knicks]. And when I'm retired, him and I will cross paths again."
