Drew Brees is a "legend" who will be sorely missed after announcing his retirement, fellow New Orleans favourite Zion Williamson said. 

Brees called time on his glittering 20-year NFL career on Sunday, with glowing tributes pouring in for the quarterback. 

And Pelicans star Williamson, fresh from a 135-115 win over the Los Angeles Clippers, praised someone whose welcoming words have stuck with him. 

Williamson was the top pick in the 2019 NBA Draft and received a special message from Brees, who has had a lasting impact on the 20-year-old.

"He's a legend in the game, I think everybody knows that he's a legend," said Williamson, who is 22 years Brees' junior. 

"He gave his heart and soul to the game. I know a lot of people are sad to see him go. 

"Drew told me I think the truest thing anybody has ever told me, my first game in New Orleans – you love your city, they'll love you right back. 

"Whenever new people come and visit, that's the same thing I tell them. That's the kind of influence he's had on me." 

Brees is a 13-time Pro Bowler and was MVP in the Saints' Super Bowl win over the Indianapolis Colts in February 2010. 

The 42-year-old retires as the all-time leader in passing completions (7,142) and passing yards (80,358).
