23 January 2002 - Where The Special One Became Special

On 23 January 2002, José Mourinho took charge of Porto, where he would establish his reputation as the "Special One."

Just three days short of his 39th birthday at the time, Mourinho had already briefly managed Benfica (2000) and Leiria (2001-02), where his analytical approach to training and success on the pitch attracted the attention of Porto. They had been the league's most successful club throughout the 1990s with eight top-flight titles during the decade, but had fallen off a bit, finishing as runners-up in 2000 and 2001. By the time Mourinho arrived, they had slipped to fifth in the table after a loss to Boavista on 20 January.

In their first match under Mourinho, at home to Maritimo in the league on 26 January, Porto won 2-1, then followed that with  five more wins out of their next six league matches to climb into third, which is where they finished the season.

In 2002-03, Mourinho's first full season at Porto, they reclaimed the league title and won the UEFA Cup with a 3-2 win over Celtic in the final, then repeated as league champions in 2004 while winning the Champions League over Monaco, 3-0.

That performance led to his move to Chelsea, where he earned the nickname The Special One after telling the English press "Please don't call me arrogant, but I'm European champion and I think I'm a special one."

24 December 2010 - Leonardo Crosses Milan's Version Of The Rubicon

On 24 December 2010, Inter announced their new manager, taking former Milan hero Leonardo away from their rival club.

A World-Cup winning Brazilian international, Leonardo made 119 appearances for Milan from 1997 to 2001, then another five in the 2002-03 before calling an end to his playing career. While there, he won the 1999 Scudetto and the 2003 Coppa Italia.

In 2008, he returned to the club in the position of technical director, then took over as manager in June 2009 after the departure of boss Carlo Ancelotti to Chelsea. But he failed to lift the Rossoneri's fortunes and rumors of an early departure swirled throughout the season. Finally, in April 2010, the club confirmed that Leonardo would depart at the end of the season.

At the time of his departure from Milan, Inter had made a change of their own, replacing departing manager José Mourinho with former Liverpool boss Rafa Benítez. But that hire lasted only six months, as a split between Benítez and the Inter board, fueled in part by the new manager's inability to live up to the standard set by Mourinho, led to his dismissal in December 2010.

Inter then brought Leonardo in to fill the vacant position, making him the fifth manager to switch from Milan to their derby rivals. His time at Inter lasted even less than at AC Milan, however, ending with his resignation in June 2011. One month later, he joined Paris Saint-Germain as their director of football, where he remains at present.

24 October 1966 - He Came, He Saw, He Conquered

On 24 October 1966, Chelsea owner Roman Abramovich was born in the city of Saratov in southern Russia. Currently one of the richest men in the world, he has spurred Chelsea to a massive haul of silverware including multiple league titles and the Champions League trophy.

Abramovich accumulated his wealth quickly, though he has been accused of using methods of questionable legality. For example, while still serving in the Soviet Army, he made money by selling allegedly stolen gasoline. By 1995, however, he, along with a partner, had acquired a controlling interest in a large Russsian oil company, paying $100 million.

In 2003, he bought Chelsea from then-owner Ken Bates. He paid £140 million for the club, who at the time were saddled with debt, and quickly steered them to back-to-back Premier League titles in 2005 and 2006--their first league titles since 1955.

Chelsea have had nine different (non-caretaker) managers under Abramovich, including Claudio Ranieri, José Mourinho, Guus Hiddink, Carlo Ancelotti, and current boss Roberto Di Matteo. Throughout, Chelsea have won three league titles (2005, 2006, and 2010), four FA Cups (2007, 2009, 2010, 2012), and the Champions League (2012).
