The Northern Irish striker predicted that Dedryck Boyata and Jozo Simunovic would capitulate if put under pressure – and he was proved right.
The creaking Hoops centre-backs had an afternoon to forget as the champions were thrashed by the Jambos at Tynecastle.
That brought an end to Celtic’s 69-game unbeaten domestic run and handed Brendan Rodgers his first defeat against Scottish opposition.
Harry Cochrane, aged just 16, and Lafferty fired in first-half goals. David Milinkovic seized on a Simunovic error to grab the third early in the second half. And Hearts made it 4-0 when Milinkovic netted from the penalty spot.
Lafferty said: “I sensed in the first five minutes that Celtic weren’t up for the game.
“In the first game of the season, I didn’t really fancy them (Boyata and Simunovic) as two centre-halves.
“I knew that when you are up against them and put them under pressure there are mistakes in them.
“I have done that, got a goal and gave other people chances as well.
“I think Celtic struggle when players get into their faces.
“I’ve always said everything will click, we will gel together and smash a team. If someone was to tell me that team would be Celtic then I’d have laughed.
“We spoke the whole week about trying to put them under pressure from the first minute until the last and that’s just what we did.
“Celtic are a team who, if you show too much respect, the result could have been 4-0 to them.
“We believe in ourselves and the manager showed belief with the way he set up the team.
“I am happy with my own performance but don’t take anything away from every single player on the pitch.
“From the goalkeeper up to Cole Stockton when he came on.
