Chelsea manager Jose Mourinho has warned against expecting too much too soon from new signing Juan Cuadrado as he suggests the Colombia international will not be in condition to prove his real worth until next season.

At the same time, the Portuguese boss has insisted he is not concerned about Eden Hazard's contract negotiations, with talks ongoing for the Belgium international to commit his long-term future to Stamford Bridge with a new deal.

Cuadrado made a Premier League cameo during the 2-1 victory over Aston Villa on Saturday 7 February just days after completing his reported £23m move from Fiorentina on the final day of the January transfer window.

Mourinho has insisted the player will need time to adapt to the Premier League before showing his real worth and the manager refused to confirm whether he will hand the winger a chance to prove himself during the home game against Everton on Wednesday 11 February.

"He is selected," said the manager, according to the club's official website, before adding: 'I know if he will start or not but I won't say.

'It's normal, step by step, to be integrated. He needs time. I know Italy and I know the difference between Italy and England. His formation, his development, his experience – everything was in Italy.

"I wasn't expecting him to come on to the pitch against Aston Villa and destroy them. Stability, time, integration – I think we will see the best Cuadrado next year."

Meanwhile, Mourinho provided an update on Hazard's new deal after the manager revealed advanced talks in December regarding a new contract with the Belgium international.

He said: "I am buying a nice pen. I need a bit of time to go to Sloane Street and buy a proper pen. I just need time to buy the pen and after that I think there is not a long time to go!"
