Since Sir Alex Ferguson has retired, Jose Mourinho surely deserves the title of the best manager in the world.
Throughout his career, Mourinho has won countless trophies, been adored by the press and has remained cool as a cucumber (most of the time).
But none of these reasons are why he is the best around. It is the ability Jose possesses to change a game in the click of his fingers like no one else in the world can.
No disrespect to Jurgen Klopp, Pep Guardiola or Carlo Ancelotti, but they cannot do this anywhere near as effectively or consistently as Mourinho can. These men are all world class at implementing a very good playing style into their team, and managing a club and signing good players - but Jose can do all this too.
Imagine the scenario, your team are 1-0 down in a Champions League final with 25 minutes to go. Despite all the play and dominating the game, an early counter attack goal has left you behind. Who do you want whispering in your centre forward's ear, or making a substitution to find a way through - Pep Guardiola or Jose Mourinho?
It's Jose you want, because he's the master of it. He can say one thing to one man and the complexion of his side will change. Jose would be the one to rapidly alter your team's style and stun the opposition. Jose will win you games.
He is one of very few managers in history who will base his team's next phases of a key game during that same game. If his team pass the ball a lot but get no chances in the first 20 minutes, he is already thinking about being direct and quick with two changes in the last 20 minutes. It's remarkable.
Take the PSG game for example. Chelsea have done all they can and are 3-2 down on aggregate with 20 left on the clock, playing the same way for the first 70. Jose brings on Demba Ba and Fernando Torres in the latter stages, telling each one exactly what to do, where to play and how to move.
In the final minutes Ba, who has done very little in his small game time this season, hits the winner. This is no coincidence. Even after the game John Terry admitted they had practiced several situations and the tactics they could employ on Mourinho's notice.
Ba and Torres didn't have to run around and tell everyone, they latched on instantly. Mourinho knew the possible outcomes of the game before the end of the first leg. He really is special.
The only other manager who could do that in recent years was Fergie, a man who Jose knows well and admires. The difference is, now he is out the equation, Mourinho can take the spotlight - and so he should.
Guardiola couldn't alter the first leg against Manchester United. A far superior team with better players all round the pitch, it still finished 1-1. All United did was sit back and counter, but Bayern were even more predictable, pass around, move wide, run at the defence and cut it back.
That isn't an insult against Guardiola, a defensive English team are extremely hard to break down and Pep is a world class manager - just not Jose Mourinho class.
Funny how one trait can define a manager, isn't it? But that's the case here. Jose Mourinho right now is the best on the planet due to this one quality. Chelsea don't know how lucky they are.
