Celtic assistant boss John Collins explains why Scott Allan and Ryan Christie's careers will not stagnate despite lack of game-time

Collins is unconcerned about either player despite the fact that neither has started a league game for the Scottish Premiership leaders.

Celtic assistant manager John Collins has insisted that the likes of Scott Allan and Ryan Christie will not have to watch their careers stagnate despite their struggles to earn a place in Ronny Deila's squad, the Daily Record reports.

Both of the players moved to Parkhead in the summer - though Christie returned to former club Inverness Caledonian Thistle on loan for the first part of the campaign - but neither has managed to start a single game in the Scottish Premiership for the Hoops.

But Collins has denied claims that their lack of game-time for the Bhoys will have a detrimental impact on their potential by suggesting that the work the club do on the training ground can prove just as intensive as playing for the first-team.

"Ideally you want people to develop every week and sit the test but when you are not playing then the test is to train well," he told the Record.

"He [Allan] is playing against better players in training than sometimes he'll face in matches.

"The training ground is stretching them very much."

Given their lack of experience at the highest level, it is perhaps no surprise that Deila is taking a more tentative approach when it comes to integrating them into the side. 

The Hoops only enjoy a slender lead at the top of the Premiership table, and have recently come in for heavy criticism following their League Cup exit, as well as their failure to make any kind of impression in Europe earlier in the campaign.

Introducing the pair into the team on a more regular basis may damage their development as they may feel there is too much pressure on them, given the expectation at Celtic, to be able to express themselves and show why they were brought to the club in the first place.
