With the transfer window now well and truly closed, it won’t be too long until rumours start appearing, linking Celtic with summer targets.

The Hoops enjoyed a relatively successful transfer window last month, managing strengthen with Patryk Klimala and Ismaila Soro, while a number of players left on loan or permanently.

Scott Sinclair was one of the major departures from the window following his switch to Preston North End, and his move cleared a large chunk of Celtic’s wage bill, given how Football Insider revealed he was earning around £35,000-a-week.

Lewis Morgan also left the club to join MLS side Inter Miami, while the likes of Jack Hendry (BBC Sport), Lee O’Connor, Jonathan Afolabi and Conor Hazard (FourFourTwo) all left on loan.

The summer will be another important window for the club regardless of what happens in the rest of this season, but as things currently stand it looks as though the Hoops will need to strengthen for a 10-in-a-row push.

With that in mind, we’ve taken a look at four January targets who the Hoops should re-ignite their interest in, in the summer.
