The Scottish striker has netted 11 goals in 31 games this term, but he told the Celtic View that he thought his Parkhead career was over at certain times this season.
Griffiths, 24, has failed to find consistency in his performances this season, and there have been times when head coach Ronny Deila has relegated him to the bench for fairly long periods of time.
Whilst his league performance has suffered, he has been utilised frequently in cup compeitions, but he has still not done enough to warrant the lone striking role in Deila’s system on a consistent basis. Frequently used as a substitute, he has started just eight Scottish Premiership games, and there is no judging whether he will still be in Deila’s plans next season, with the Scottish giants likely to strengthen before the campaign begins.
Admittedly, Griffiths has been winning over the public in recent weeks, and judging by the increase in game time, even Deila is starting to see him as a useful figure. The forward’s goal output must surely increase if he intends to continue holding down a regular role, but this is a marked change from the beginning of the campaign - with Griffiths admitting that he was looking for a loan move away from the Bhoys, and fearing for his entire Parkhead career.
Speaking to the Celtic View, the striker said: “In the early months of the season, there was talk of me going on loan, and it did cross my mind at some stages when I wasn’t playing and was sitting in the stands.
“There were times when I thought my Celtic career was over. But I have knuckled down, worked hard and got myself back in the manager’s thoughts.”
