Travis Kelce described Patrick Mahomes as a player "always ready for the moment" after the Kansas City Chiefs quarterback's decisive touchdown pass against the Las Vegas Raiders.

Mahomes found Kelce with 28 seconds left as the Super Bowl champions won 35-31 in Las Vegas to move to 9-1 in the AFC West.

The Chiefs trailed 31-28 inside the final two minutes after Jason Witten's go-ahead score, leaving Mahomes under pressure to deliver.

The two-time Pro Bowler duly responded, leading a seven-play, 75-yard drive in 75 seconds as the Chiefs moved into range for a game-tying field goal.

Instead, Mahomes threw 22 yards for Kelce's touchdown to cap a stunning finish to the game that even drew admiration from Los Angeles Lakers star LeBron James, who tweeted: "I mean was there any doubt on that drive!?!?! No there wasn't."

"[Mahomes] is always ready for the moment,'' Kelce said. "We've got 15 back there making plays. He kind of turns it up when it matters the most.''

Likewise, coach Andy Reid never seemed in doubt.

"I've got Pat Mahomes,'' Reid said. "You give me a minute and a half and I'm pretty good right there. We can roll.

"I'd take him over everybody and I'm lucky to have him.''

Mahomes finished 34 of 45 for 348 yards, two touchdowns and an interception, while he rushed for 16 yards on four carries.
