Having been installed as Celtic's interim manager following the departure of Brendan Rodgers to Leicester City, Neil Lennon might have asked for an easier introduction to life back at Parkhead.
The Scottish Premiership leaders travel to Hearts on Wednesday evening as they aim to preserve or extend their eight-point lead over Rangers in pursuit of an eighth consecutive title.
Lennon, who managed Celtic between 2010 and 2014 then Hibernian between 2016 and 2019, has been the victim of a number of unsavoury incidents at Tynecastle.
May 2011
Title-chasing Celtic arrived at Tynecastle on the penultimate day of the Premiership season aiming to put some pressure on leaders Rangers.
They achieved this with a comfortable 3-0 win but the match was overshadowed by what happened after Gary Hooper had scored Celtic's second goal.
Hearts fan John Wilson, 26, emerged from the stands and made his way to the technical area where Lennon was standing.
There he aimed a punch at the Northern Irishman's head before being dragged away by security.
Wilson was charged with a sectarian attack on Lennon but this charge was not proven, though he did receive an eight-month jail term for breach of the peace.
The attack was witnessed by 16,000 spectators at Tynecastle and thousands more watching the match live on television.
February 2014
Lennon wasn't even managing one of the teams involved the second time he suffered problems at the Edinburgh ground.
The Celtic manager was watching the League Cup semi-final between Aberdeen and St Johnstone on a scouting mission.
Lennon sat in Tynecastle main stand along with Celtic first-team coach Garry Parker and Hearts assistant manager Billy Brown.
Sat near Aberdeen fans, Lennon was spat on, verbally abused and had plastic cups and coins thrown at him. Stewards relocated him closer to the pitch but the problems continued and Lennon was eventually forced to leave after an hour.
His representative Martin Reilly said: 'This is the second time that something has happened to Neil at Tynecastle, so there is obviously something wrong with the security.
'The last time it was on the pitch, and now he's not even safe to sit in the stands. It's absolutely unbelievable. This wouldn't happen at any other stadium in Scotland.'
Lennon himself described the events as 'unsavoury and uncalled for.'
October 2018
At the conclusion of a highly-charged Edinburgh derby, Hibernian manager Lennon was struck by a coin thrown from the home stands at Tynecastle.
Lennon's frustration had been growing all night with one of his players sent off in an increasingly fraught contest and it looked like Hearts had won it at the death only for the goal to be disallowed for offside.
Lennon turned to the crowd and started celebrating with arms raised, appearing to tell Hearts fans to sit down.
He was then struck on the jaw by a coin thrown from the stands and fell to floor clutching his face.
Lennon said after the match: 'My jaw is throbbing. I'm very, very angry. I'm fizzing about it.
'I'm alright. They must have a few quid up here because it was a pound coin.
'But it's no laughing matter, I hope somebody deals with it and I'd like to meet the guy face to face.
'It's all disgraceful. The players are doing their job and trying to entertain people, I don't understand the mentality of any supporter who wants to throw things at people.
'I have seen plenty of it at the weekend as well and it's very unsavoury and needs to be stopped.'
And in the aftermath of the incident, vile graffiti reading 'Hang Neil Lennon' appeared on a wall in the Russell Road area of Edinburgh, close to Tynecastle.
