French outfit Lille are set to bid £5 million for Celtic central defender Jozo Simunovic, according to The Scottish Sun.
The 24-year-old joined the Hoops for £4 million back in 2015.
Celtic boss Neil Lennon will be keen to keep the man who has largely been a mainstay in the side since his return to the club.
Lille defied the odds to finish second in Lige 1 last season. They will now look forward to a Champions League campaign during 2019/20.
Lennon is already short of options at central defence and losing Simunovic would represent a blow.
The Hoops boss has added Christopher Jullien to his ranks this summer, but Lennon will hope to pair the Frenchman alongside Simunovic.
A nine-cap Croatia Under-21 international, Simunovic will probably be attracted to the French top-flight, although Lennon will hope to convince him of his importance to Celtic.
Losing Simunovic would represent a tough pill to swallow for Celtic.
The £5 million on offer from Lille would be ambitious at best. Having signed him for £4 million, Celtic would almost certainly demand more.
Losing a central defender at this stage would not be ideal, however.
Celtic are looking desperately short at the back as it is and Simunovic’s departure would only add to that worry.
The Croatian is good on the ball, can tackle and is not afraid to stick his head where it hurts.
At this stage Lennon needs reinforcements, not departures and the club must do all they can to keep hold of Simunovic.
