Wisdom originally joined Liverpool in 2008 at age 14, having previously come up through the Bradford City youth system.
The defender made his Liverpool debut in 2012, going on to appear 19 times while scoring one goal under Brendan Rodgers in his first senior campaign.
That goal came on his debut, a 5-3 Europa League win over Young Boys, with Wisdom earning further first-team appearances in the weeks following, including an appearance in the Merseyside derby against Everton in October 2012.
His second season saw him make just three appearances to start the campaign before being loaned out to Derby County, starting a string of loans away from Anfield.
It was during that time that Wisdom featured for West Brom, Norwich and RB Salzburg before joining Derby on a permanent deal in 2017.
Since making that move, Wisdom has made 58 appearances across all competitions for the Championship side, scoring one goal.
Derby currently sit eighth in the Championship following Saturday’s victory over Reading, with Wayne Rooney scoring the game-winning goal last time out.
