Chelsea manager Jose Mourinho holds the rather enviable record of having never lost a Premier League fixture at Stamford Bridge. Today's opposition, Tottenham, turned up in West London looking for their first win away to the Blues since 1990 - that's before I was even born- and unsurprisingly left empty-handed, licking their wounds after a hefty 4-0 drubbing. That brings the Blues gaffer's total to an incredible 75 home fixtures in the top flight without defeat.

With Chelsea once again going so strong under the Portuguese, we at Football Fancast are prepared to make the audacious claim that Mourinho will never lose a league fixture at Stamford Bridge. In case you don't believe us, here's three reasons behind our logic, illustrated throughout the course of today's ninety minutes against Spurs.

1. The defence.

Chelsea currently don the best defensive record in the Premier League, having conceded just 22 goals in 29 games. It beats the next-best goals conceded margin, Everton's at 27, by quite some way. They also have thirteen clean sheets - very impressive.

 

We all know Mourinho favours the more stable and functional approach when it comes to philosophy, which resultantly makes the Blues an impenetrable bunch and leaves them something to fall back on even when they aren't playing well, as highlighted by these Twitter enthusiasts at half time, when the game was still at nil-nil;

 

 

2. Substitutions.

Jose Mourinho is famed for his astute use of substitutions. The Portuguese has even claimed he can 'smell a goal coming' in the past, and makes his switches from the bench accordingly. And who can forget, back in his first tenure at Stamford Bridge, the Special One making a triple substitution after just half an hour!

Well, the Blues boss pulled off another substitution master-class yet again today. With Chelsea looking rather rigid going forward and lacking some guile in the middle of the park, Mourinho threw on young Brazilian Oscar during the interval, and the positive effects were immediate;

 

 

3. Luck.

Sir Alex Ferguson was often accused of being dubiously fortunate throughout his Manchester United tenure, and the same can be said of many a-great manager, or rather in this case, a 'Special' manager. Jose Mourinho might not like to admit it, but it's safe to say that luck, fate and fortune played a more than significant role in Chelsea's first two goals of the afternoon, which in effect decided the final result. Check them out for yourselves;

The penalty was particularly telling, as it reduced Tottenham to ten men despite it clearly not being a foul.

Could fortune favouring the brave be the real secret behind the Special One's continuous successes at home?
