Leigh Griffiths is a great Celtic striker in the making, according to former Bhoys goalkeeper Pat Bonner.

The 25-year-old forward opened the scoring in Wednesday's 2-1 win over Hearts before setting up his side's second goal, scored by Tomas Rogic.

"He had a lot to do in that particular first goal, but his mind was working and you could see what he was thinking," Bonner told BBC Sport.

"Even when he went through, he had the composure to knock it past the goalkeeper. That's the making of great strikers and great Celtic strikers."

Griffiths's goal in the Scottish League Cup quarter-final at Tynecastle has taken his tally to 12 in 22 games this season.
