Brendan Rodgers, the Celtic manager, has offered an insight into his working psyche as he revealed the relentlessness of his own drive to sustain the club’s dominance.

The 45-year-old is just one game away from penning another chapter into the Scottish history books this season, an addendum that would top last term’s Treble winning season with Celtic. Rodgers became only the third man in the Parkhead side’s history to enjoy a clean sweep but that he did so without losing a game placed him in a unique niche.

If there was relief at delivering such a joyful campaign in his inaugural season, it did not last long. Only days had passed following Tom Rogic’s dramatic winning goal at Hampden when Rodgers was fretting about how to kick on, how to follow on from essentially the perfect domestic season.

Rodgers watched his side put on a swashbuckling performance to clinch the title against Rangers on Sunday afternoon, but as the players set off to party in Tenerife and enjoy the fruits of their labour, the Parkhead boss was far more conservative in his celebrations.

“Look, the bad times are just around the corner,” he said. “So, no, I can’t really sit back and enjoy this. I had this last season, you know. We won the treble against Aberdeen and then three days into my break, I had this fear of complacency. It’s a fear I always have.

“We produced a document on the traps we must not fall into to ensure we succeed over the longer term. So, you can’t enjoy it too much.

“When you are gone, when you are out of it, you can look back and all the nice moments can become clearer for you. But not right now.”
