Chelsea has been in a very dominating form at least in relation to the Premier League as Jose Mourinho and his squad faced almost no difficulty in winning the 2014-15 season but there are some key things which need to be done if Mourinho wants to extend the form that his team is going through.

One of the main things is to keep hold of Eden Hazard. The Belgium midfielder has already received numerous individual awards including the Premier League Player of the Season as he scored 14 league goals and provided his teammates with 9 assists.

Eden Hazard has turned into one of the most important players in Stamford Bridge as the player is always causing trouble to the opposition’s defence with his fast legs and dribbling abilities, its hard to deny the fact that Hazard is one of the best players not only in England but in the world.

At the age of 24, Hazard practically has his entire career left ahead of him and keeping hold of him is crucial for Chelsea.

Real Madrid, Barcelona, Manchester City, Manchester United, Bayern Munich and PSG are all of the top clubs that have the financial freedom to make a huge cash offer for the Belgium player but trying to convince Jose Mourinho on letting one of his star players leave would be almost impossible to do.

When it comes to signing players, Spain has turned into a market where Chelsea manages to secure outstanding talents. Chelsea snatched Diego Costa from Athletic Madrid and this signing was a success for Jose Mourinho and his squad as Costa managed to score 20 league goals in 26 appearances.

There are a few more players that are currently performing for Spanish club which is the case of: Raphael Varane, Diego Godin, Koke and Antoine Griezmann. Some of these players might be harder to sign than others but if the offer is good enough, Chelsea might just be able to sign a few of them in the summer.
