Time is the Key for Roman Abramovich's Dream to Transform Chelsea into the Barcelona Mould

why Chelsea's ambition to transform themselves into the Barcelona mold has failed as of yet...

Roman Abramovich has been subject to many a dissections and criticisms since his introduction to English football way back in 2002. "Chelsea is our club, not your toy" - Words once famously put up by a group of Chelsea fans perhaps quite aptly defined their frustration on the Russian's drastic moves at the helm of the club every now and then. Something that they felt made their beloved team suffer.
Yet, for the Chelsea's faithfuls, Abramovich's blue revolution was the very reason the club saw the most remarkable period of success in its 107 year old history. Under the guidance of Jose Mourinho and Abramovich's money power, Chelsea emerged from the shadows of Arsenal's "Invincibles" and began a 3 year domination, conquering virtually all fronts in England, missing out on only the Champions League.
From a team dwelling merely on the upper half of the table, and claiming their stake for European places (The Blues finished 4th in the season before Roman took over), Chelsea was transformed into a winning machine. A team that could consistently challenge for the top honours throughout the season and can be considered among to continent's elite.
However, when Mourinho was sacked mid-way into his fourth season at Chelsea, apart from Roman's hastiness and lack of patience, it brought forward yet another aspect of the Russian billionaire - his lofty ambitions for the club; albeit not the most ideal way to show it.
  Mourinho's sacking showed that the owner wanted something more at the club!
Abramovich dreamed of a Chelsea that would not only be a winning time but also a one that was beautiful to watch. Something that Mourinho couldn't bring into the club. Soon, there was a distinct change in the club's transfer policies. While in the earlier part of Abramovich's era, the club secured the signings of the Drogbas, Essiens and the Ballacks, the post-Mourinho period saw the club chasing the likes of Jose Bosingwa, Daniel Sturridge,Ramires, Juan Mata and Fernando Torres; players who are not necessarily known for out-muscling the opponent but are predominantly associated with their agility and skill on the ball. They even wanted Robinho and Kaka; deals which never really fructified. 
In their ruthless quest for success, the club changed several managers since then but never quite managed to find the combination of the both.
Perhaps Carlo Ancelotti's first season was the closest they came, where the side notched up a memorable domestic double, scoring a staggering 103 goals in the league. However, with the team ageing, the second season couldn't really bear the same result and he was immediately replaced by Andre Villas-Boas.

The 33 year old apparently attempted a similar model of attractive football but failed miserably, with the core of team getting no younger and lacking the pace to adjust to the 'tiki-taka' style of play. In one of the most notable observations during his brief stint was that Chelsea targeted several of Barcelona's academy players. A clear hint that the club was aiming for a transformation in their style.
Further, it was quite evident that the Blues were ready to invest their money in the youth squad, by bringing in the likes of Lucas Piazon from Sao Paulo and Ulises Davila from Chivas to name a few, in their quest to organize a new Chelsea side for the future.

Nevertheless, despite their efforts, the theme hasn't quite materialised for Chelsea as of yet. But why?
Well, to start off, Chelsea have probably been spot on with their policies in transfers. It is quite apparent that club believes that the players like Juan Mata and Fernando Torres will form the core of the team once the current 'old guard' is not a part of the squad anymore. With the increasing addition of the skillful players in the youth setup, they would hope that these young starlets could then make the transition into the first team, while they already have a core consisting of players of similar style but more experienced. 
However, this process is more or less a 'buying process' rather than the club developing players from its academy like in the case of Barcelona. Chelsea are buying their way both in the youth setup as well as in the first team. Now, the basic deficiency in this process is that the players then take a longer time to gel and hence the transition period takes an even longer time than usual, as is the case with Chelsea right now. Plus, there is always the risk of money going down the drain, if the huge amounts are invested on the wrong players, who although were expected to make it big but never could.
While Abramovich's ambitions are creditable, but it is imperative for him to understand that it is not always possible to secure immediate results even when the right steps are taken. So, no matter which manager he brings in, Chelsea wouldn't be able to completely transform into Roman's Dream Team until and unless the whole "transition phase" is complete; and also provided that the money was used to secure the signatures of exactly the right players. 
It is certainly a very difficult task in hand for Chelsea; something that could very well not turn out be according to plan, even if their initial steps were correct. It is as unpredictable as walking on the thin ice, and it remains to be seen whether Abramovich's patience stays by his side. It is a combination of both time and luck that the club needs in order to get their ambitions fulfilled.
