Super Bowl LVII MVP Patrick Mahomes insists the Kansas City Chiefs "ain't done yet" after claiming their second title from the past four seasons with Sunday's 38-35 win over the Philadelphia Eagles.

The Chiefs celebrated with their fans on Wednesday with an open-roofed bus parade which culminated at Kansas City's Union Station.

Mahomes vowed on stage at Union Station to the crowd that the Chiefs were only just starting.

"I just want to let you all know that this is just the beginning," Mahomes said.

"We ain't done yet, so I'll make sure to hit y'all back next year and I hope the crowd's the same.

"We're back again. We're back again. Before we started this season, the AFC West said we were rebuilding.

"I'll be honest with you, I don't know what rebuilding means. In our rebuilding year, we're world champs."

Mahomes' latter comment was in reference to expectations that the Chiefs would slip from contention in the 2022 season with wide receiver Tyreek Hill traded to the Miami Dolphins and safety Tyrann Mathieu not re-signed among other changes.

Chiefs tight end Travis Kelce has been vocal about those who wrote off the Chiefs and reiterated that sentiment, while insisting this was "the best season of my life" after a career-high 16 touchdowns from 20 starts inclusive of the regular season and playoffs.

"The haters were saying that the Chiefs would never make the playoffs. The haters were saying the Chiefs were done. Done," Kelce said.

"In all reality, this was the best season of my life. I owe it to you guys. I owe it to the guys on this stage. I owe it to everybody… Everybody's asking: Is this a dynasty? It's been a dynasty."

The Chiefs have made the AFC Championship Game in each of the past five seasons, winning on three occasions and losing the other two in overtime.
