Celtic manager Neil Lennon has acknowledged that winning the Scottish Premier League is essential for his long-term future at the club.
"I think it is imperative that we do win it. Three years without the title is a long time for us," said Lennon.
"From my own point of view, if you go two years as an Old Firm manager without a title, it might be very difficult to keep your job.
"The pressure of the job is always the same - win the league."
Celtic were pipped to the title by Rangers on the final day of season 2010/11, the Ibrox side's third consecutive championship.
They also lost in extra-time to their old rivals in the final of the Co-operative Insurance Cup but finished the season by lifting the Scottish Cup at Hampden by beating Motherwell.
"Some of the football we played last season was fantastic and we want to continue that," said Lennon.
"We weren't far away from achieving a domestic treble, but we fell short in two competitions and we want to improve on that next year.
"The expectation level is going to be greater because of the progress we made last year and that is a credit to the players.
"They have to accept that challenge and take it on as I do as a manager.
"If you can win a double or treble, brilliant, but to win the league is a must really.
"I have had one go at it. The fans might get a bit fed-up if we miss out on a second one."
The coming weeks are not likely to match the level of transfer activity of a year ago when Lennon was busy welcoming players such as Beram Kayal and Emilio Izaguirre as he built a squad for his first full campaign.
However, Lennon let it be known that he is in the market for a goalkeeper, a centre-forward and perhaps one other player too.
Newcastle have rejected a £1.5m bid to take Fraser Forster back to Celtic, where he was on loan last season, and Lennon is keen on 19-year-old Kenya midfielder Victor Wanyama, of Belgian side Germinal Beerschot.
"He is a player who has come to my attention and he is a good young player," he said.
"We have not pursued that matter any further other than as an option.
"But if the club can get the opportunity to speak to him then we welcome that.
"But there won't be wholesale changes. We are really happy with the majority of the squad and we only need to bring in one or two."
For his own part, the Celtic boss said he was "delighted" to have agreed a new deal at Celtic and hopes that assistant Johan Mjallby and first-team coach Alan Thompson will soon be in a similar position.
"They are in talks at the minute and hopefully that will be resolved by the end of the week or early next week," added Lennon.
"It is important for continuity and it is important for me to have people that I brought in, people that I trust and people whose opinion I value, to carry on at the club next to me."
