left the studio in stitches at expense during historic final victory against Manchester City. The veteran presenter, currently in hot water over his social media activity, poked fun at Rooney's managerial record during half-time at Wembley Stadium.
Palace led City 1-0 through Eberechi Eze's 16th-minute opening goal, which proved to be the winner on a historic afternoon as the Eagles lifted their first-ever major trophy. Lineker, Rooney, and fellow pundits Glenn Murray and Micah Richards were discussing how Oliver Glasner's side would set up to retain their lead in the second half.
During the analysis, Richards asked Rooney: "Being a manager and you're 1-0 up... what do you tell the players at half-time? Do you change the way they play?"
But then Lineker interupted with a cheap jab at the Manchester United legend, stating: "His team were never one up!"
Lineker, Richards and Murray could be heard laughing out loud behind images from the match as the former apologised for his comment.
"Let's get back to the game," Rooney softly responded before expanding with his viewpoint on the topic as Pep Guardiola's ultra-attacking outfit chased the lead.
City were unsuccessful and suffered a second consecutive FA Cup final defeat, having lost 2-1 against their rivals, United, last year.
The fallen Premier League champions are now confirmed to go without a major trophy for the first time since the 2016/17 season.
Guardiola was gracious in defeat, congratulating Palace and insisting he was more content with his team's performance than against United last year.
"We didn't score, so congratulations to Crystal Palace for the victory - we did everything," Guardiola told BBC One.
"Today, we were more aggressive. If you're not going to score goals, you're not going to win."
He added: "They performed really well, much better than last season against Man Utd.
"Football sometimes is like this. At the end, with Claudio Echeverri, we created a chance.
"We controlled really good in transitions. Yes, unfortunately, we couldn't win, but congratulations, Crystal Palace."
Omar Marmoush produced a costly miss from the penalty spot before half-time, having been appointed rather than City's usual taker, Erling Haaland.
Guardiola remained coy on the eye-catching decision after full-time, claiming he had no say in who stepped up for the key moment.
"I don't know, I didn't speak to them. They made a decision. They decide," the City boss explained.
