Derby County striker Nathan Tyson says he is "embarrassed" by the injury-hit start to his Rams career.
Tyson, 29, joined in the summer but has been plagued by groin problems and has only made two brief appearances.
But he played the final 10 minutes of Saturday's game against Ipswich and is desperate to make up for lost time.
"It's not just been a nightmare, it's been embarrassing. You join a new club and you want to impress and show what you can do," he told BBC Radio Derby.
"I'm so eager to achieve something here and be a success at this club and to have that taken away for me has been very hard."
The pacy forward's career has been hampered by injury and Tyson hoped his move to Pride Park from fierce rivals Nottingham Forest would be a chance to lose his injury-prone reputation.
But the nine minutes he played against Ipswich and a 25-minute run-out against Forest in September is the only first-team football he has managed for his new team.
"It will be very exciting for me in 2012," Tyson added. "The new year is something I am really looking forward to.
"I've missed being in and around the lads so much. Hopefully in the next few games, I might get a start."
