When Jose Mourinho returned to Chelsea for the second coming, many believed the Portuguese' style of play would spell the end for certain players.
Chelsea played some of the most exciting and technically gifted football in last season's Premier League with players like Oscar, Juan Mata, David Luiz and Eden Hazard, all establishing themselves as top Premier League talent.
There was a freedom about Chelsea's play under Rafael Benitiez as the Spaniard rotated a young squad who had to play almost 20 games more than their domestic opponents by the end of the season.
Many critics believe that this expressive, expansive style of play, much more suited to La Liga, is not something Chelsea can maintain under Jose Mourinho.
Chelsea's Player of The Season for 2012/13 was Juan Mata. The Spanish midfielder was the Premier League's top assist creator last campaign and established himself as potentially the best player at the club.
On Wednesday against Aston Villa, Mata played his first match of the season but was replaced in the 65th minute after spending the night on the periphery of the game.
Mata looked off-the-pace which is acceptable after playing non-stop football since the London 2012 Olympic Games for the Spanish Olympic team.
However the Chelsea number ten is rumoured to be worthless under the new Stamford Bridge boss. In my opinion Mata is the most talented player at Chelsea Football Club, along with David Luiz.
Both players were crucial in last season's third placed finish and Europa League triumph, but more importantly the two are fan-favourites after creating a bond with the Chelsea supporters over the last few years.
It seems incomprehensible that Chelsea would sell any of their most valuable assets. After all, money has never been an issue under owner Roman Abramovich.
The club also refused to even talk to Barcelona after the Catalan side made their second bid for David Luiz in two seasons, which is a promising sign suggesting the Brazilian is important to the squad and the owner.
For those who believe Mourinho can only manage strong, rigid, defensive teams, think again. As manager of Real Madrid, Mourinho's side played fluent, attacking football and only really showed defensive brutality when facing rivals Barcelona.
With Chelsea, Mourinho will try to allow the attacking potential to continue flourishing but what is certain is that the Portuguese will improve the defensive stability behind the club's forward players.
The first two Premier League games were typical of this. The Blues didn't play particularly well but played at a high pace when called upon and looked far more solid in midfield and defence than in games last season.
Mourinho has a wealth of talent to pick from but Chelsea fans beware, it will take at least a season for the best 11 to reveal itself and more importantly, with Jose at the helm, don't expect to see your side going for five and six when the game is already won.
What I am sure of though, is that Juan Mata and David Luiz will become Chelsea legends.
