Greg Rutherford said Jade Jones put too much pressure on herself and is a "complete star" of Team GB despite her shock first-round taekwondo defeat on Sunday.
Jones, who is a double Olympic gold medallist, was defeated by Rio bronze medallist Kimia Alizadeh of the Refugee Olympic Team.
Olympic gold medallist and Eurosport pundit Rutherford said: "She's clearly put a bit too much pressure on herself there and it's really difficult not to. She's a complete star of Team GB she has had a fantastic couple of games and she's been having a difficult time.

"We've been saying it from the get-go that certain athletes are going to react differently to different scenarios and clearly for Jade this hasn't worked out but she's a top quality athlete and an absolute legend within the world of Team GB, so I hope she can come away from this and not feel too down.
"It is heart-rending of course but she has to remember that there's a lot of people looking up to her that she is a complete star and she's had a fantastic career so we'll see where she goes from this."

Jones said not having her family there to support contributed to the early defeat. "I just felt like I put too much pressure on myself going into it and I really did feel it, more than I expected on the day," Jones said. "Not having my family there to kind of push me out of that fear zone really did affect me and I'm just gutted that I couldn't do more.
"For me, I do love a crowd, and I do love my family being there so it was a struggle and I did miss them being there. I call them 'Team Crazy' - the ones that have been to every Olympics," she added.
