Los Angeles Rams quarterback Jared Goff was left hurting after his team's loss to the New England Patriots in Super Bowl LIII on Sunday.

Goff completed 19 of 38 passes for 229 yards with an interception as the Rams suffered a 13-3 loss in Atlanta.

The 24-year-old said the offense failed to live up to expectations, rueing their performance after the Rams managed to hold Tom Brady and the Patriots to 13 points.

"Kills, kills and it hurts me so much just knowing how well our defense played against that team, against Tom, to play that well defensively and us not hold up our end of the bargain," Goff told a news conference.

"It's our job to score points and we didn't do that."

Goff was leading the Rams on a potential game-tying drive in the fourth quarter, but he was intercepted by Stephon Gilmore.

While he was keen to move on, Goff said there were several moments he wished he could have again.

"It's the toughest loss I've ever had. It kills. It's terrible," he said.

"There are some good things you can take from it, but right now there's nothing.

"It's a game I wish I would've played better, I wish we would've played better offensively as a whole, I wish I could have a million plays back but there's nothing you can do about it, you've just got to learn and move forward."
