Colchester manager Kevin Keen says the job has "probably" been more of a challenge than he anticipated.
The 48-year-old is yet to achieve a League One victory after taking his first managerial role in December.
When asked by BBC Essex if he regretted taking the job, Keen said: "100% no.
"I saw it as being a fantastic challenge, probably a little bit more of a challenge than I thought, but that's because I haven't been able to get the results the club needed."
He added: "I really believe the club is going in the right direction. I think we've got some fantastic young players."
The U's have only won one match since Keen replaced Tony Humes - a 2-1 win over Charlton in the FA Cup.
Colchester are currently bottom of the table, eight points adrift of safety, having avoided relegation on the final day of last season.
"It's not just this year that the club has struggled. I think it's a bit of a knock-on effect on that," said Keen.
"Perhaps the squad that was created this year was a little bit unbalanced, not just in terms of ages but also position-wise, and we've not been able to address that too well.
"I've tried very hard to recruit certain players, players who I thought would improve the group and that hasn't come off - perhaps a reason for that is that we're lying bottom of the league.
"And mentally it's tough because it's been a while since we've won a game. Until you actually win a game and get that monkey off the back it's quite difficult."
