Celtic's Derek Riordan is frustrated at his lack of first-team action and may seek a loan move in January.
Riordan played 90 minutes against St Mirren in the CIS Cup
The 23-year-old striker moved from Hibs to Celtic Park in June but has managed just three minutes of SPL action and one start in the CIS Insurance Cup.
Riordan told the Daily Record: "I will have to consider doing something in January if I am not playing.
"It is hard to train all week and not even make the bench. It's the worst feeling ever."
Riordan finished top-scorer at Easter Road for three seasons running but is yet to find the net for his new club.
"It is a frustrating and annoying time for me and not to be playing in Celtic's first team is really bugging me," he continued.
"I know I have to be patient and wait for my chance but we are nine games into the season and I have played three minutes.
I was embarrassed when Hibs came to Parkhead and I was sitting in the stands
"I've not been used to this situation. For three years I had regular first-team games with Hibs.
"Old Firm games and Champion League matches have come and gone and I haven't featured in them and that really hurts because I signed for a massive club to be part of that.
"I was embarrassed when Hibs came to Parkhead and I was sitting in the stands, not even part of the squad.
"Then there was the Hearts game when I didn't get off the bench despite the fact I have a good scoring record against them."
Riordan's three minutes of SPL football came as a substitute on the first day of the season against Kilmarnock.
And he was an unused substitute, along with fellow summer signing Jiri Jarosik, in Sunday's 1-0 win at Falkirk.
