The Celtic boss is reportedly keen to reunite with his former Liverpool man.

According to the Scottish Sun, Celtic are looking to make a move for Liverpool defender Jon Flanagan this summer, and the defender should push for the move.
He has had a difficult two years at Anfield after starring under Brendan Rodgers, battling his way back from a serious injury to feature at the end of last season.

He will need further first team football to continue his progress though and that is unlikely to come at Anfield in the near future.
Nathaniel Clyne is very much first choice at the club, and Jurgen Klopp is thought to be a big fan of the England international, meaning Flanagan would face a fight to replace him in the side.
Aside from that, while the Scottish Premiership is a competitive league, it is definitely less challenging than the Premier League and may be the perfect place for him to step up his rehabilitation process.

There is also Brendan Rodgers to consider. The current Celtic boss handed Flanagan his first team chance at Liverpool and knows how to get the best out of him.
Of course, Liverpool are unlikely to want to let him go, especially given how much of a fan favourite he is at Anfield.
Their decision to sell Jordon Ibe shows they will allow players to leave if it is for the best of their career though, and a move to Celtic would be the best for Flanagan at this stage.
