Neil Lennon admits the hairdrier treatment was required with his players, following Celtic’s 0-0 draw at Hibernian over the weekend.
The Hoops were disappointing at Easter Road on Sunday, throwing in a lethargic performance and dropping two points in the process.
While the Scottish Premiership title is still in sight, a dip in performance level has been evident in recent weeks.
Lennon often has the reputation as a manager who will show his anger to his players, but he claims that isn’t his style at all.
The former Celtic midfielder admits that type of behaviour was required after the Hibs game, however, telling the Daily Record that complacency has set in:
I’m following in great footsteps and maybe it’s not Brendan’s way, the way I approach games.
Listen, I have this reputation as being a hairdryer-type manager. I’m not at all.
But there are times when they need to be told and Sunday was one of those days.
Next up for Lennon’s side is the visit of Kilmarnock on Saturday lunchtime, with victory all bit wrapping up title glory once again.
A much improved display will be required, though, as will be the case in the Scottish Cup final against Hearts on May 25th.
Celtic's top 5 players against Hibernian
5. Scott Brown
Brown kept things neat and tidy in the middle of the park, without ever being spectacular.
4. Jonny Hayes
Hayes was Celtic’s most threatening attacking player, on a day when they failed to fire in the final third.
3. Scott Bain
Bain had a reliable afternoon and made one big stop to deny Oli Shaw.
2. Kristoffer Ajer
It was another strong showing from the young centre-back, who has shone all season.
1. Jozo Simunovic
Like Ajer, Simunovic outshone his more attacking teammates, making one crucial block. Missed a late chance to win it for Celtic.
