Chelsea have always been synonymous with success, particularly since the arrival of Roman Abramovich. The club have collected 13 pieces of silverware since his arrival, including three Premier League titles.
However, the club has been on something of a barren run recently, not tasting glory in the league since the 2009-10 season under the stewardship of Carlo Ancelotti. To put a time scale on this that will make sense to fellow Chelsea fans, it's been four managerial departures since they last lifted the Premier League trophy.
Recent seasons have been dominated by the two Manchester clubs, but there is reason for Chelsea fans to believe that the Blues could end this spell. Here are a few:
Chelsea got their business done early, identifying problem areas and striking a deal as soon as possible. A new striker was essential, and the arrival of Diego Costa could be the addition they have desperately needed since Didier Drogba's departure. Although just in case it doesn't quite work out, Mourinho brought Drogba back to Stamford Bridge to provide competition.
Furthermore, the dearth of a creative influence in the deeper midfield role has been addressed following the arrival of Cesc Fabregas, who could be even more vital than Costa and Drogba in increasing our potency in front of goal, as it was often our lack of creation against compact sides that led to a lack of goals.
Felipe Luis appears to be an apt replacement for Ashley Cole at left-back, which is probably the best compliment I could give him.
These are strong, proven European players who have addressed all the weaknesses which were evident last season. Credit must also go to Chelsea for tying up the deals early on, giving the players as much time to settle as possible.
There is no doubt that Petr Cech has been a fantastic servant for Chelsea, but there is no doubt that every Chelsea fan is excited by the prospect of potentially seeing young protege Thibaut Courtois line up between the sticks for us this season.
The Belgian has been outstanding in his three years on loan at La Liga champions Atletico Madrid, even being labelled by then-Real Madrid coach Jose Mourinho as the best goalkeeper in the world. He would almost undoubtedly be the best stopper in England, and competition with Cech will hopefully see whoever starts raise their performances.
Stability. Not a word commonly associated with Chelsea, I'll admit. But for the first time in a while there has been very little upheaval at Stamford Bridge this summer. Same manager. No overhaul of the playing squad. The young players vying for the attacking midfield roles have all had time to adapt to English football. The centre-back partnership of John Terry and Gary Cahill will be allowed to continue to blossom and new contracts are on the table for the duo. All is looking good.
Contrast this with Tottenham and Manchester United, who have new coaches and still appear to be chasing new players, who will have little to to settle and gel. Meanwhile Liverpool have gone about flashing their chequebook, spending in excess of £100million in an attempt to fill the void left by the irrepressible Luis Suarez - reminiscent of Tottenham's flurry of new arrivals last summer. Very much a gamble.
Manchester City and Arsenal have also enjoyed similar stability, but I would argue that neither has strengthened as well as Chelsea.
The Special One
The Happy One. Whatever he wants to be called. You may question the man's methods, but there can be no questioning his track record. Even achieving a third-placed finish and a Champions League semi-final berth with an unfancied squad is a demonstration of his nous.
I hope to see a more adventurous style of play from the Blues this season, but Mourinho knows what he needs to do to win and, with a stronger side at his disposal, would well see his side succeed this season.
I think it is fair to say that there has seldom been such a feeling of optimism at Stamford Bridge and, if this talented squad can reach its potential, this could well be a season to remember for Blues fans.
