John Terry is preparing to leave Chelsea when his contract expires at the end of the season, according to the Daily Mirror.

The report states that Terry is unhappy with the club as they are yet to offer him an extension with less than six months left in his current deal.

Last month, the former England international was hopeful that a new contract will be made available for him to extend his stay in west London. But so far, indications have not been made by the Chelsea hierarchy to begin negotiations in order to hold on to their skipper beyond the current campaign.

The 33-year-old, who has made over 400 Premier League appearances for Chelsea is nearing towards the final stages of his career and the club reportedly consider offering their talisman a one-year extension which will also cause the defender to take a hit on his current earnings of £170,000 per week.

According to the report, Terry is keen on retaining his place in Chelsea squad for three more years and is hopeful of remaining a one-club man before deciding to hang up his boots.

The skipper graduated from Chelsea's youth academy in 1998 and went on to establish himself as a vital part at the heart of the defence for the west London club, captaining the side to three league titles.

Jose Mourinho is understood to be keen on making new additions to his side's back four after his reported pursuit of Kurt Zouma from St Etienne. The 50-year-old had contacted the 19-year-old in order to convince him to make the move to the west London outfit.

The Portuguese tactician could bring in Zouma as an ideal replacement, should his talismanic skipper leave Chelsea at the end of the season.

Apart from Terry, Chelsea's other title winning players Frank Lampard and Ashley Cole are also having their contracts expiring in June this year.

The former Real Madrid manager insisted that he is not worried about the fact that these players will be out of contract at the end of the season while indicating that an extension will be doled out to them before the season concludes.

"Their desire to play for this club, nobody has doubts about it. Everything is very calm [and] at the end of the season, probably before that, the offer will be on the table," Mourinho explained.
