Shaq's got an ally in his war on Scottie Pippen ... Matt Barnes ... who says the NBA star is delusional if he thinks the Bulls would beat the Lakers in a battle of the greats.
Barnes didn't know about all the personal shots Shaq and Scottie were taking at each other when we saw him at LAX yesterday, but he definitely had an opinion on the 5-on-5 debate.
Shaq claimed the 5 best Lakers of all time would smash the 5 greatest Bulls of all time ... Pippen disagreed. So Shaq called him a woman, a bum and Michael Jordan's bitch.
For the record, Matt's fought alongside Shaq in the past ... bet he'd be down to do it again.
