With Sky Sports reporting on Thursday that Jose Mourinho had signed a contract to become the next manager of Manchester United, Reds and fans of their rivals alike were lighting up social media with differing views on the man himself.
Love him or hate him, Mourinho has certainly collected his share of trophies over his career and he has the type of personality that won't be overwhelmed by the size of the job he's taking on at Old Trafford.
While rebuilding United, Mourinho will also renew hostilities with a few of his old sparring partners, including the following:
When Mourinho first came into English football with Chelsea in 2004, Arsenal were the reigning champions and the self-styled 'Special One' didn't waste much time in getting under the skin of their manager Arsene Wenger. With the Frenchman constantly complaining about Mourinho's conduct incessently in the press, Mourinho famously said: "I think he is one of these people who is a voyeur. He likes to watch other people. There are some guys who, when they are at home, have a big telescope to see what happens in other families. He speaks, speaks, speaks about Chelsea. He should be worried about [Arsenal]. He's worried about us, he's always talking about us. It's Chelsea, Chelsea, Chelsea, Chelsea."
On his return to Chelsea in 2013-2014 he labelled Wenger "a specialist in failure" after gleefully making note of Arsenal going eight years without a trophy. The lead up to first meeting between the Gunners and United in the coming season should be interesting.
After masterminding Inter's unlikely victory over Pep Guardiola's all conquering Barcelona side in the 2010 Champions League Semi-Final, Mourinho made the move to the Catalan club's greatest rivals, Real Madrid, to face off against the former Spanish international on a more regular basis.
During Mourinho's three seasons in Madrid, the rivalry between the two sides was arguably cranked up another notch as Mourinho tried, largely, in vain to get under the skin of the Barca boss.
Despite Barcelona being largely in the ascendance, Mourinho's Madrid did manage to win the 2011-2012 La Liga title, the only league crown Madrid has captured in the past eight years.
Guardiola left Barcelona following that season, and yet despite the two men no longer facing off against one another Mourinho couldn't help but take another dig at him in September 2014 when he cracked:
"When you enjoy what you do, you don't lose your hair, and Guardiola is bald. He doesn't enjoy football."
The two will resume their rivalry in Manchester next season, with Guardiola heading over to City.
Even kindly current Leicester City manager Claudio Ranieri fell afoul of Mourinho, with the two having run-ins during the Portuguese bosses time at Inter.
Ranieri dared to suggest that Mourinho was showing Italian football a lack of respect by not showing up for news conferences early on in his time in Milan. Not being the type of person who enjoys being talked about in other than glowing terms, the new United boss retorted:
"I studied Italian five hours a day for many months to ensure I could communicate with the players, media and fans. Ranieri had been in England for five years and still struggled to say 'Good morning' and 'Good afternoon.' Who is he to tell me what to do?"
As the manager of the current English champions, I think it's safe to assume that Ranieri will be hearing more from Jose in the coming season.
