Managing Bolton Wanderers is just as challenging as being in charge of Celtic, says boss Neil Lennon.
The ex-Northern Ireland international, 44, has been at Bolton since replacing Dougie Freedman in October 2014.
Lennon spent four years as manager of Celtic, winning three league titles, two Scottish Cups as well as managing in the Champions League.
"It's as big a challenge as I had at Celtic, in a totally different way," he told BBC Radio Manchester.
"Yes there are frustrations there, there is no question of that, but every manager will tell you the same thing.
"All pressure is relative - people have pressure of getting promoted, winning cups, avoiding relegation."
Lennon discussed a number of issues during BBC Radio Manchester's Monday Football Hour, including:
- Striker Adam Le Fondre wanted to re-sign after a successful loan spell last season, but it did not work out because of finances
- Free agent and former captain Kevin Nolan will probably not be returning
- A striker was at the club on Monday discussing terms about a move
- Lee Chung-yong, now with Crystal Palace, was one player he wished he had been able to keep
- Hopes to recruit loan signing Prince-Desir Gouano on a permanent deal at the end of the season
Asked where he hoped the club will be in two or three years' time, he said: "Hopefully challenging for promotion, but it's going to take a bit of time.
"It takes time to build a team and it takes time to change the squad if you want to call it that. If there are players not in your thinking, you have to move them out to make way for others.
"Hopefully a bit of investment comes in eventually. The board are working away in the background at that."
