Alan Shearer has started his first job as a football manager, at his old club Newcastle United. He's already taken his first training session at the club.
Fans in Newcastle hope Shearer will be able to save the team from relegation. He has eight Premier League games to manage it, starting with Chelsea at home.
Alan Shearer played his first game for Southampton aged 17. The first time he started a match for the Saints he scored a hat-trick, against Arsenal in a 4-2 victory.
After more than 150 games for Southampton Shearer agreed a big-money move to Blackburn Rovers in 1992. At the time, the £3.3m fee was a British transfer record.
But that fee was smashed four years later, when Shearer moved to his home-town team Newcastle United. This time the £15m deal was a world record.
Shearer was a massive success at Newcastle, bagging more than 200 goals in 10 years at the club.
Shearer was also a big player for England, scoring 30 goals in 63 games for his country. He retired from the team after Euro 2000 to concentrate on his Newcastle career.
Shearer's final match for Newcastle was against local rivals Sunderland and he scored a penalty in the game. But an injury forced him to retire from football in April 2006.
After he finished playing Shearer joined the BBC as a football expert. He appeared on Match of the Day and was a big part of the football team on telly.
