But the head coach has once again reiterated that Enzo Le Fee still has a pivotal role to play for the Black Cats this season, despite the fact the Frenchman was a substitute for the Premier League opener against West Ham.
Le Bris started summer recruits Granit Xhaka, Habib Diarra and Noah Sadiki in midfield against the Hammers and was thrilled with the performance of the trio, as individuals and a collective.
But he insists he will need to rotate and freshen up his midfield throughout the season, with Le Fee and Dan Neil still set to play prominent roles.
"We started with three but we need four, five or six for the season," said Le Bris.
"The starting XI for the first fixture will be different maybe this weekend, maybe one month. It's always like that, so we can't predict the exact dynamic or the future.
"We know we will need three, four, five, six players in this position to ensure consistency."

Explaining the summer overhaul of the midfield, Le Bris said: "When we planned the squad for recruitment, we thought it was really important in our head that we found players who wanted to run, because the demand of this league is really high.
"But their running needs to be smart. It's not just running everywhere. The balance is really positive with two young powerful runners [Sadiki and Diarra], good footballers as well, and an experienced player [Xhaka] behind them able to manage different tactical problems, help and give advice.
"The balance worked well for this game but I repeat Burnley is a different challenge and then there are 36 others."
Asked whether he was at all surprised by Sadiki's excellent display and by how quickly his midfield gelled, Le Bris said: "With young players, especially in a young squad, it's always a new experience.
"I had my expectations but after that you have to experience it, and it was really positive.
"The way they worked together...I think these players have learnt our game model really quickly. It was very positive."
