Brendan Rodgers spoke of his desire to build a legacy for both Celtic and Scottish football, but insisted he might not be given the time to see all his work come to fruition.
The Northern Irishman has presided over a resoundingly successful first season at Parkhead in which he has led the club back to the Champions League and pursued an unbeaten path towards a domestic treble.
Rodgers enters Sunday’s Premiership game with Rangers knowing a win will extend the gap between the sides to 36 points and edge his team closer to a sixth successive title, but he insists he remains susceptible to the innate volatility of football management.
Brendan Rodgers wants to build a legacy at Celtic but fears he won’t be able to see it through
He said: ‘The plan for my time here is just to do the very best that I can. Whether that’s for one year or another four or five years, I want to raise the standard that hopefully pushes the club to the maximum.
‘I’m on a one-year (rolling) contract, so you can’t predict a manager’s stay. You can’t say how long you are going to be here. On a Saturday you walk on water and on a Monday you’re the devil.
‘A manager would love to say that you can stay and build something, but modern society doesn’t really allow you to do that.
‘So for all you’d like to say this or that, you can only promise that while you are here that you do the very best that you can.
‘My obligation is for a legacy here. So what do I want to leave?
‘That compared to the first day I walked in, the club is in a better place than when I walk out.
If Rodgers’ side defeat Rangers they will open up a margin of 27 points at the top of the table
Rodgers went to Celtic Park last summer and has already won the Scottish League Cup there
‘Can I develop players? Can I influence players to play the game in a different way to what they maybe thought before? If that spreads to helping the Scottish game, then great.
‘And, hopefully, I can bring some sort of profile to a game that everyone was starting to ridicule.’
Moussa Dembele will seek to continue his rich vein of scoring form against Rangers on Sunday, but Rodgers might have to fend off interest from Liverpool, Arsenal, Manchester City and Chelsea, all of whom will have scouts at Parkhead.
Caretaker boss Graeme Murty will stand opposite Rodgers but the Celtic boss insists the imminent appointment of Pedro Caixinha as the next manager at Ibrox will not ‘alter his own approach to the job’.
The 44-year-old added: ‘Hopefully, you can see developments in what I am trying to do here at Celtic. You have to keep moving to be successful and it’s not reliant on what the other one is doing.’
