After spending the 2012/13 season on loan at BL6 from Liverpool, the midfielder joined the club permanently in August 2013, having previously spent his whole career at his home-grown club , apart from a brief loan spell at Leicester City in 2009.
A member of the Liverpool Under-18s squad that lifted the 2006 FA Youth Cup, defeating Manchester City in the final, Spearing captained the young Reds the following year as they defended their crown, this time lifting the cup after beating Manchester United on penalties.
He made his competitive first team debut in December 2008, coming on as a substitute in a 3–1 UEFA Champions League win against PSV Eindhoven, before appearing in the Reds' 4–0 win over Real Madrid later on in the competition.
After breaking into the Reds midfield during the 2010/11 season under Kenny Dalglish, Spearing was an unused substitute as Liverpool won the League Cup Final in 2012, while he would start in the FA Cup Final later that season as the Reds lost against Chelsea.
But after the arrival of Brendan Rodgers at Anfield, the midfielder was allowed to leave the club on loan after finding himself down the pecking order.
Making 39 appearances during his loan season at the club, his performances saw him named Wanderers' Player of the Season and the Championship Player of the Year at the 2013 North West Football Awards.
Registering 46 years appearances in 2013/14 following his permanent return to Macron Stadium, Spearing wore the captain's armband on occasion during the latter stages of the campaign in the absence of Zat Knight.
Named captain at the start of the following season, he spent the second half of the campaign on loan at Blackburn Rovers.
Returning to Macron Stadium at the end of the year, the midfielder made 23 appearances for Bolton in 2015/16 before his campaign was ended prematurely.
Reclaiming his place under Phil Parkinson, Spearing scored a spectacular winner over Sheffield United on the opening day of the 2016/17 season, before inheriting the captain's armband after Darren Pratley was ruled out with a fractured leg.
