Flamini clashed with Ozil during defeat to Bayern Munich.
"When you're a journalist or you're a fan seeing it from the outside, it's difficult to interpret it," he said. "But Mesut is one of my closest team-mates and we were on the pitch.
"It was not about arguing it was just about communication. Mesut is a winner, I'm a winner; we were both fighting because we just wanted to give everything to the team to make sure we defended properly.
"It was about communication, but at the end of the day it proves to everyone that we really wanted to win and we're winners. It's important, as you want a team with character, not a team who doesn't react."
