The 30-year-old played just one game in three months for the Scottish Premiership leaders.
Ronny Deila has claimed that he has seen an improvement in Scott Brown's form in recent weeks after recently admitting that he brought the midfielder back into the Celtic side too soon following his lengthy spell on the sidelines, The Scottish Sun reports.
The Hoops skipper featured just once in three months earlier in the campaign due to knee ligament damage (via The Scottish Sun), but has been back in the first-team since January.
However, the 30-year-old has struggled at times since his return, and Deila previously conceded that he may have rushed him back too quickly.
But the Norwegian has now suggested that he is starting to see the player that has led the Bhoys to so much success in recent times.
"Broony's been out for three months and now he has played a lot of games lately," he told The Scottish Sun.
"He is going in the right direction and it is tough to be out for as long as he was and then go straight back in.
"I think that the last games have been better and I know how much he means to us - in the dressing room and on the pitch as well.
"On the ball he can be even braver and get forward but defensively he is very good for us - he is always taking out the right spaces and he plays an important role for us."
With an opportunity to go eight points clear at the top of the Scottish Premiership on Saturday, it appears that Deila's men are well on course to securing their fifth league crown in a row.
However, while the title race may be starting to look like it could soon be over, Celtic still have a tricky tie ahead in their Scottish Cup semi-final clash with Rangers.
The atmosphere that is generated for an Old Firm contest means that it will be up to players like Brown to lead by example to ensure that the squad remain focused on winning the encounter and putting themselves one game closer to earning another trophy, meaning that Deila will need his captain to find his best possible form for the occasion.
