Kansas City Chiefs head coach Andy Reid is "okay" with Travis Kelce's displays of anger.

The 35-year-old NFL star - who is engaged to pop singer Taylor Swift - has occasionally let his frustrations get the better of him in the early weeks of the new season, but Reid insists he isn't bothered by Travis' on-field attitude.

Reid told reporters: "The question came up yesterday about Travis and the intensity and all that.

"'Is he frustrated or not frustrated?' Well, he's seen how the offense works. So when things aren't going the right way, he's very aware of that.

"He's a pretty smart guy and he's been doing it longer than anybody else on this team has been doing it. He wants to make sure that he gets that point across to the guys, and so he does that.

"I'm OK with that part."

Travis confronted his coach at one point during the Chiefs' latest game. However, Reid welcomed his passion during a post-match interview.

The coach told reporters: "I love Travis' passion, man.

"We didn't have enough of it in the second quarter. It wasn't where we needed it to be, so, within reason, he knows when to back off the pedal and knows when to push it, too."

Meanwhile, Patrick Mahomes - Travis' teammate at the Kansas City Chiefs - previously claimed that Taylor has helped to make the NFL franchise a "worldwide team".

The sports star told Time magazine: "[The Chiefs] went from a nationwide team that was kind of global to a full global worldwide team. That came from Taylor's fanbase."

Patrick also admitted to being wowed by Taylor's work ethic.

The 30-year-old star - who is one of the best players in the NFL - observed that she's "never not working".

He said: "I've met a lot of famous people now in my life. Taylor's probably the most down-to-earth person that's been on that stage for that long.

"She's never not working. Even when she's taking her downtime, she's working on something. Shooting a music video or singing a song or writing a song. You can see it by how she talks."
