The former Celtic captain was embroiled in a feud with the striker while he was in Glasgow.
The pair were involved in a series of heated exchanges during derby clashes.
And Brown had revealed he had a real dislike for Diouf – even if he still can’t quite put his finger on the exact reason.
However, the former Scotland international joked he has Diouf to thank for his ‘Broony’ celebration and the best yellow card of his career after celebrating with his arms outstretched in front of the striker.
On the No Tippy Tappy Football podcast – quizzed on Diouf – Brown said: “My friend! I really didn’t like him, I don’t know what it was.
“He had that little bit of arrogance about him as well. I think he wanted to wind me up as much as what I wanted to wind him up.
“To be fair I got a celebration out of scoring against him, he was standing still and I just put my arms out and it was the best booking of my whole career.
“We had a lot of battles over the years and I enjoyed it. He was a good player back in the day but I wanted to show him what I was about.”
Brown also couldn’t resist trolling Rangers as he corrected Tim Sherwood on the terminology for matches between Rangers and Celtic.
The Celtic hero refuted Sherwood’s ‘Old Firm’ reference as he quickly cited the ‘Glasgow derby’ moniker adopted by Celtic supporters.
Sherwood said: “I have been up, I’ve not been to the Old Firm. I’ve been up to scout a few players.
But Brown quickly interrupted: “The Glasgow derby…”
