Celtic lifted the Scottish Cup on Saturday afternoon, beating Motherwell 2-0 in the final. With that win, Rodgers added another Scottish treble to his CV in what has been a hugely successful spell with Glasgow's green and whites.
Nevertheless, the Welshman still feels there's room for improvement: "They can improve in terms of performance level, league and points."
"We lost more games than last year and we drew more games than last year, so there's lots we can do better.
"I need to push them even harder next year and that's going to be important. However, the club can enjoy this year. It's a monumental achievement, it's a historical day and one that will be with everyone forever.
"We'll come back in a few weeks' time and go again," he added.
Rodgers then congratulated his players on their historic feat: "I'm immensely proud. I thought the players were fantastic today and I'm just so happy for the players, the supporters and the staff.
"They put so much in. it's been a really tough, competitive season for us this season, but to come out of it again with three trophies, it fills you with pride."
