Stuart Armstrong has admitted to Celtic's official website that he has only recently started to feel like his normal self, after a slow start to the season.
The central midfielder has struggled with injury for much of the current campaign, but he has been eased back into the fold by Ronny Deila of late.
Armstrong has stepped off the substitutes' bench in Celtic's last two fixtures, and says that he is keen to play a bigger role now that he has returned to full fitness.
“I’m really eager now to just get back involved,” he said. “It was nice to get half-an-hour against Hamilton and get back into it and to feel good.
“That was the first game where I felt my normal self again so if I can continue that, there are a lot of games coming up and hopefully I can play my part at some point."
Armstrong was acquired by Celtic in January 2015, and made a positive impression towards the back end of last season.
The former Dundee United man was handed a prominent role in Deila's team upon his arrival, and went on to make 18 appearances for the Bhoys.
This time around, he has played 10 times, but most of those appearances were made while he was short of fitness and, as a result, his form hasn't been up to scratch.
His return to full health will be a major boost for Celtic, though, as the side look to knock Aberdeen from the summit of the Scottish Premiership table.
