Jose Mourinho's not happy.
You already knew that though. The Chelsea boss hasn't said as much but you just know. You know by the tone of his voice in interviews and press conferences.
You know by his comments regarding Arsenal and their spending over the past few years. You know by seeing his sarcastic laughing at refereeing decisions during last week's Community Shield at Wembley and this weekend's draw with Swansea.

You know by the way he has singled out a member of his medical team for particular criticism and very public chastisement in the wake of said draw. You just know.
You also know because it's season number three and it's Mourinho.
The first stint
His first stint at Chelsea was the first time the Portuguese had entered into a third full season at a club. 18 months at Uniao de Leiria. Two and a half years at Porto. Nine games at Benfica.
Way back in August 2006, Chelsea were defending the Premier League title and Mourinho was entering into his third season at the club. Mourinho though, wasn't happy. He didn't say as much but you just knew.
You knew by the comments he made. You knew by the way his demeanour changed, becoming more and more combative, defensive, argumentative, even controversial. You knew by the fact that he had £30 million worth of over-the-hill striker thrust upon him in the form of Andriy Shevchenko. You just knew.
He would, of course, go on to complete the season, and even begin another before a very public, very bitter breaking up following a 1-1 Champions League draw with Norwegian side Rosenborg, just a month in to the 2007-2008 season.
Fast forward to 2012 and Mourinho was embarking on season number three at Real Madrid with a brand new four year contract in his pocket and a La Liga title on the mantelpiece but he wasn't happy. He didn't say as much.
You just knew that the eye-poking and the increasing number of run ins with the Spanish press indicated something wasn't right. You knew because, well, it's Mourinho.
Fast forward again and you get to August 2015. Chelsea are champions. Season number three. It's unfair to say that Chelsea limped over the line last season but it's certainly correct to say that Chelsea's form, and performances in the first half of the season were much better than those after the turn of the year.
Before Christmas the question was 'is this Mourinho's greatest Chelsea side?', now the question is 'what is up at Chelsea?'. This weekend's comments about his medical team's lack of understanding of the game of football and subsequent reshuffle suggests something is bubbling below the surface.
Chelsea's transfer activity this summer has been alarmingly low key. A striker is needed. You know that. Mourinho knows that. Diego Costa has a hamstring that belongs to a man in his thirties, not a sprightly 26 year old.
Radamel Falcao looks as though injuries have taken their toll and Loic Remy is just not good enough. Mourinho also feels that a centre half is needed. John Stones is the man but Everton are digging their heels in. He hates that.
Mourinho gets what he wants. Nobody can tell him no. Not Frank Arnesen in 2006, Avram Grant in 2007, Florentino Perez in 2012. Not Everton in 2015. This is how it ends with Mourinho. Long, drawn out, spiteful and very, very public.
Is this the beginning of the end for Mourinho and his love affair with Chelsea? Is this the long goodbye? It certainly looks like it. He hasn't said as much. You just know.
