Brendan Rodgers says Celtic defender Maik Nawrocki is back in training and "doing well" as he continues his injury recovery.
The 22-year-old sustained a hamstring strain in August against Kilmarnock and has not featured since.
Nawrocki was not included in the Parkhead side's Champions League squad due to the nature of his injury but now seems to be on his way back to action.
Rodgers told Celtic TV: "He’s [Nawrocki] doing very well and trained over the last week or so.
“We only have Stephen Welsh and Liel Abada who will hopefully be back in December time.
“Thankfully that’s starting to ease off and we’re starting to get numbers back in what’s going to be a busy part of the season.
“You always know you will have injuries, I just think at the beginning of the season that aligned with new players coming in and trying to adapt and settle was the challenge."
Rodgers is also relishing his side's upcoming clash against Atletico Madrid. They take on the Spanish giants on matchday three of the Champions League group stage as they search for their first points in this year's competition.
Diego Simeone's men currently sit fourth in LaLiga, having already tasted success in the first Madrid Derby of the season.
"They’re an outstanding team and Diego Simeone has done an outstanding job over many years at Atletico Madrid," he continued.
“He’s been there over a decade and been really successful so we know the challenge and that they are a very good side.
“For us, in our two games, we have been really competitive and we’re not far off from being a good side at this level.
“There were still elements in those games that I was pleased with and we will go into this game and look to give absolutely everything and see if we can learn from the previous two games.”
