Former Celtic hero Stiliyan Petrov has told The Scottish Sun that left back Kieran Tierney has been 'a real bonus' for the Bhoys this season.
Tierney, 18, has come up through the ranks at Celtic Park, and fans have been hoping for a young prospect to emerge as a first-team star for some time.
James Forrest has shown flashes of brilliance, but there has certainly been a dearth of young players coming up through the ranks at Celtic - only for Tierney to try and reverse that trend.
The teenage left back has earned a place in Ronny Deila's side this season, even displacing Emilio Izaguirre in defence, despite the Honduran's long-standing run as the club's first choice left back.
Having been left out in the 0-0 draw against Kilmarnock on Saturday, many believe that Tierney is in line for a start against Ajax in the Europa League on Thursday.
Now, former Bhoys star Stiliyan Petrov has told The Scottish Sun that he has been impressed with Tierney's performances, stating that he should start against Ajax.
The Bulgarian also added that Tierney's displays will have a major impact on the club's transfer plans, given that fans had wanted to see a new left back signed to challenge Izaguirre - but with Tierney coming through, Petrov says Celtic are settled at left back and can now spend their money on other areas of the pitch.
"Kieran Tierney impressed me against Molde," said Petrov. "He had great energy and enthusiasm and his willingness to get on the ball really caught my eye. He also delivers a lovely ball into the penalty area. He has fine technique and is a real asset. I’d like to see him against Ajax."
"The way he has arrived on the scene in the past few months has been a real bonus for Celtic. Solid left-backs are not easy to find and can also be expensive, so Kieran may well have solved a problem. I believe they have been looking to strengthen in that area for a period of time and Kieran’s performances may mean they are now absolutely fine in that area and don’t need to spend money on a left-back. That money can be used for elsewhere in the team," he added.
