The starting back four may not change at all, but there will be inevitable departures.
David Luiz: The best defensive transfer in January in all of football. Can be brash at times, but has the quality to become world class. Plus, he won't be cup tied for Chelsea next season.
John Terry: Legend, captain, not going anywhere. Even at 30, he's still one of the most reliable defenders in the world.
Alex: At 28, he's in the prime of his career. Sometimes nagged with injuries, but Chelsea would be ridiculous to transfer a player of his quality. Great with free kicks from distance and a beast in the air. Alex will be with the Blues next season and for the foreseeable future.
Ashley Cole: Arguably the best LB in the world. Aging, but still consistent. Needs to stay out of the tabloids and quit being a distraction. He will be in the starting 11 all next season.
Branislav Ivanovic: Developing into a world class defender at 26; definitely not leaving the Bridge anytime soon.
Patrick Van Aanholt: Just signed to a four year deal. Chelsea have invested in the future with the 20- year-old Dutch international.
Paulo Ferreira: The 32-year-old Portuguese RB day's are numbered. He has been tremendous over the years, but I feel his time has come to depart in the summer.
Jose Bosingwa: Rumored that he wants to leave Stamford Bridge and head to Italy or Germany. Most likely, he will leave the Blues in the Summer.
Yuri Zhirkov: Good supplemantary player, will be needed to defend the flanks if Bosingwa and Ferreira leave. Occassionally scores and will be with the Blues in 2011-12.
