Despite this, there are still key areas of the squad that will need to be addressed in the summer.
Let's take a look at the latest players linked with the Blues.
---UPDATED FRIDAY FEBRUARY 21---
Jamie Sanderson at The Metro has reported on a shock deal that would see Jose Mourinho sign a 40-year-old centre-half. Inter Milan captain Javier Zanetti is out of contract at the San Siro in the summer and it is thought that Mourinho would like him to come to Stamford Bridge for a season before becoming a key member of the backroom staff.
Jamie Sanderson at The Metro has picked up on comments from a friend of Edinson Cavani which suggest that the Uruguayan striker is looking to leave Paris Saint-Germain this summer. According to the report, the friend has said "If clubs want to sign him, it would soon be time to make a move."
The Guardian's Rumour Mill reckons that Mourinho could try to sign Bayern Munich forward Mario Mandzukic this summer. With Robert Lewandowski on his way to Bavaria, the 27-year-old will find his playing time even more restricted than it is at the moment, and he could present a cheaper option than the likes of Edinson Cavani.

Jamie Anderson of The Express has reported that Jose Mourinho is keen to reunite with Sami Khedira at Stamford Bridge.
A knee injury put paid to a reunion last summer, but it is understood that Khedira is keen to work with Mourinho again.
