Claudio Ranieri will always be welcome back at Stamford Bridge.
The Italian helped to lay the foundations that have led to Chelsea being the successful club they are today.
He signed Frank Lampard and helped bring John Terry through. He also identified Arjen Robben and Didier Drogba as potential signings; both players would become key figures at Stamford Bridge.
Ranieri’s departure came in unfortunate circumstances but his work - which included helping to choose Cobham as Chelsea’s new training base - was vitally important.
The 67-year-old returned on Sunday as his Fulham side took on Chelsea in the Premier League.
The task for Ranieri, appointed Fulham’s boss in November, is simple: keep the Cottagers in the top flight.
A 3-2 win against Southampton in his first match in charge was an encouraging start as Ranieri looks to avoid the drop.
Raniei wasn't happy with Fulham fans' chant
He’ll be backed along the way by Fulham supporters who dream that he can achieve the same at Craven Cottage as he did at Leicester City.
But they’ll have to get back in his good books after a moment during the game against Chelsea.
Per Chelsea journalist Mark Worrall, Ranieri wasn’t happy when Fulham fans started to sing: “Ranieri, he comes from Italy, he f***ing hates Chelsea.”
Worrall observed: “Claudio isn’t happy and signals them to stop.”
You can imagine Ranieri feeling pretty embarrassed about that.
Ranieri reflected on time at Chelsea
The Fulham boss gave a fascinating interview in which he reflected on his time at Chelsea in the week.
"My job was to make Chelsea always high in the table, but we didn't have so much money to spend,” he told Sky Sports.
“I remember my third year, we didn't sign any players. We achieved the Champions League, finished fourth in the table, and then Roman Abramovich arrived.”
And with him, an incredible amount of money.
Nothing has been the same since.
