Wayne Rooney regretted taking Manchester United's late penalty against Liverpool, which he missed on a great save by Simon Mignolet.
Juan Mata had already scored two goals and Rooney said he should have let him go for the hat-trick.
Rooney has scored 14 of his last 19 Premier League penalties.
"Very happy tonight. Fans were amazing. @juanmata8 great goals. Should of let him take penalty," wrote Rooney on Twitter.
