Celtic manager Neil Lennon is confident he will be safe in the Tynecastle dugout on Sunday when he returns to the stadium for the first time since he was attacked there by a fan in May.
The Hoops' 3-0 Clydesdale Bank Premier League win over Hearts was overshadowed by the incident in which Jambos supporter John Wilson emerged from behind the technical area to clash with the Celtic boss.
All eyes will be on the Hoops' technical area on Sunday but, speaking at Celtic's training ground in Lennoxtown, Lennon said: "I'm sure measures will be in place and it (dugout) will probably be the safest place for me to be on Sunday. I'm hoping that anyway. I am basically more concerned about the way we play and getting the three points."
He added: "The only thing I'm nervous about is my team doesn't play as well as we can. It is a tough game and it is a difficult place to go and win.
"But it was an embarrassment for a lot of people and I don't want to go through that again."
Meanwhile, manager Paulo Sergio admits that his Hearts revolution has stalled after conceding his side have gone backwards in recent weeks.
The Hearts boss was angered by the sloppy defending which led to the 2-0 Clydesdale Bank Premier League defeat to St Johnstone last weekend, as the Tynecastle players continue to struggle with the new coach's expansive style.
"It seems in the last 15 days we have taken one step forward and then two steps back," said the 43-year old, whose team lost to Ayr United in the Scottish Communities League Cup before the Perth defeat.
"Before that, I was seeing the team growing up every week. Three weeks ago we were making progress and going the right way - we need to get back to that.
"We weren't aggressive enough in attack and haven't been making good decisions. Even if we win against Celtic I will not be happy, because I don't want a two-faced team. We are showing one thing at home and another away from home."
