Neil Lennon has blamed a relentless fixture schedule for Celtic’s ongoing injury problems this season.
The Hoops have been battling across four competitions in 2018/19, with domestic and European commitments testing the depth of their squad.
Lennon has replaced Brendan Rodgers at Parkhead and he arrived without the services of numerous key men.
The likes of Tom Rogic, Callum McGregor, Ryan Christie and Olivier Ntcham have all been unavailable, to name but a few.
Kieran Tierney has been out for large periods, Odsonne Edouard has also been absent, as have captain Scott Brown and Nir Bitton, who has missed 11 months of action.
Speaking to the Daily Record, Lennon says a heavy workload has taken its toll as the campaign has progressed, with previous seasons also playing their part:
We have a lot of injuries at the moment and I think that’s down to the volume of games these guys have been playing over the past two or three years, plus very little rest and recuperation.
We have Champions League qualifiers in mid-July, so the close season is very, very short for these guys now.
With the success they’ve had they’ve played in every domestic game in every domestic cup competition, Europe, and then with their countries. It’s a big, big ask for them.
Some of them show every now and again little signs of fatigue which I understand. I can see it in our players at times.
Once the international break is done and dusted, Lennon will hope to see more key players become available.
The Hoops host Rangers in a mouthwatering contest on March 31st.
