Stars who have shown it can still be done after turning 40 as Cristiano Ronaldo celebrates milestone: Winning a Super Bowl, becoming world heavyweight champion and a trio of Olympic medals

Cristiano Ronaldo welcomed his 40th birthday donning a £4,000 compression boot, which indicates he still plans on playing football well into the fifth decade of his life. Ronaldo is still scoring goals while playing for Al-Nassr in Saudi Arabia, and leading the line for the side he signed for in January 2023 having left Manchester United. The veteran has scored 23 goals and assisted four times this season and is leading the Saudi Pro League in goal contributions, with his side currently third in the league standings.

He moved to Saudi after falling out with former United manager Erik Ten Hag, who he accused of disrespecting him in an exclusive interview with Piers Morgan before his Old Trafford departure. Although the Saudi league does not grab as many eyeballs as European football, it is commendable what Ronaldo is able to do at his age, with the five-time Ballon d'Or winner still going strong. The Portuguese star is not the only athlete to continue their career into their 40s and achieve great things. Here, Mail Sport takes a look at some of the others.

He won his first Super Bowl at the age of 24, but his long career saw him repeat the feat six more times with two of them coming after the age of 40.

Brady's last Super Bowl win came in his time with the Tampa Bay Buccaneers, and the legendary QB became the oldest Super Bowl MVP at the age of 43, when he helped his side win the trophy in 2020. After 22 seasons, Brady finally announced his retirement on February 1, 2022. However, just 40 days later he made a comeback and became the oldest quarterback to start an NFL game. In what was his final season, Brady was unable to inspire the Buccaneers to another Super Bowl win, which led to him deciding to retire from the game for good on February 1, 2023.

Kareem Abdul-Jabbar entered the NBA as one of the most decorated college basketball players after helping the University of California win three National Collegiate Athletic Association championships. He lived up to his expectations when joining the NBA and delivered the Milwaukee Bucks their first-ever championship, also starring for the Lakers, helping them win five championships in his time there.

Playing for the Lakers, Abdul-Jabbar had a plethora of talent on his roster, but they faced some tough sides throughout his career. He became the oldest Finals MVP when he won the award after his performance in the 1985 Finals against Celtics at the age of 38. He continued playing after that and won two more championships in 1988 and 1989 after turning 40, while also making it into the All-Star team in his final two seasons.

Tiger Woods introduced himself to the world in style when he became the youngest Masters winner in 1997 at Augusta National in record-breaking fashion.

George Foreman was widely known as 'Big George' in boxing, for no reason more than his extraordinary boxing ability.

He won a gold medal in the heavyweight division at the 1968 Mexico Olympics and proved his prowess once again when he defeated Joe Frazier to win his first Heavyweight championship in 1973. Foreman lost the title to Muhammad Ali in 1974, but he carried on fighting and, in 1994, after several other victories, beat Michael Moorer and win another heavyweight championship. Foreman was controversially stripped off the title after refusing a rematch that the IBF scheduled against Axel Schulz, but he continued boxing for a few more years before eventually retiring at the age of 48.
