The Uruguayan striker moved to the Catalan club in a £65million move in 2014 after seeing the Reds' title challenge collapse in the latter stages of the previous season.
Rodgers said on Sky Sports' Goals on Sunday that Suarez was always going to make a move away from Anfield for greener pastures.
"Transfers were a group decision; it was certainly not something where I would have the sole final say," said Rodgers.
"It's difficult because you want a player in but if the player is not on the list, you'd have to take someone.
"It was a huge blow to lose Luis. I built the team around him. Ideally, after the second season when we'd just missed out [on the title], you keep your best players, add one or two and then hopefully go on and win it.
"Unfortunately, we lost a world-class player, and you've seen his impact at Barcelona.
"I think his mind was made up.
"We needed a player who could press at the top, not just a goal-scorer, because Luis was giving us so much more than that."
