Ex-Chelsea star Kezman looks completely unrecognisable with shaggy grey beard

Former Chelsea star Mateja Kezman has undergone a transformation that makes him look unrecognisable from his playing days at Stamford Bridge.

Kezman was signed by Jose Mourinho in the summer of 2004 and was handed the No.9 shirt previously worn by Jimmy Floyd Hasselbaink, who had moved to Middlesbrough.

The Serbian striker arrived at Stamford Bridge with an impressive scored record for former club PSV Eindhoven, finding the back of the net 105 times in 122 appearances in the Eredivisie.

That helped PSV to win two Dutch league titles, earning him a £5.3million move to Chelsea, though he was unable to replicate the form that had convinced the Blues to sign him.

He scored just seven times in 41 appearances before being sold to Atletico Madrid after just one season in London.

HAVE YOUR SAY! Who should be Chelsea's top target in the January transfer window? Comment below.

Before he left though, he did win the Premier League with the Blues, which was their first title under Jose Mourinho.

Kezman also came on as a substitute in the 2005 League Cup final against Liverpool, which Chelsea won 3-2 to secure a famous double.

The striker scored the winning goal in that game, ensuring that he went down in club folklore despite his short stay at Stamford Bridge.

He was either clean shaven or had a closely-trimmed beard during his year in England, but now looks totally unrecognisable.

Kezman now has a big, shaggy grey beard and tattoos covering the sleeves of both of his arms, having retired nine years ago.

The beard is bushy and two-tone, with huge white sideburns and a black goatee to complete the 'Castaway' look.

That is not all though, with Kezman's hair appearing to going much thinner and lighter from his time at Chelsea.

Kezman's radical transformation has shocked many Chelsea fans, with some joking it is down to Mourinho's management.

"Fallen on hard times after Chelsea it seems," one fan wrote.

"Either that or lockdown has hit him hard..." another replied.

"Look what Jose did to Kezman, guys," a third joked.

After leaving Chelsea, Kezman went on to have spells at Fenerbahçe, Paris Saint-Germain and Zenit Saint-Petersburg before finishing his career in Hong Kong.

After retiring at the age off 33, he became a football agent, with his client list including Manchester United target Sergei Milinkovic-Savic.

And despite his short stay at Stamford Bridge, Kezman has since insisted that his year with Chelsea was the happiest of his career.

"Chelsea was the best thing in my career. That was the climax of my career, for sure. Living and playing in London was something that I will never forget," he told Sky Sports in 2011.

"I don't know if I made a mistake because I moved away so quickly. Maybe I do and maybe I don't regret it, but I always believe in my decisions.

"But the transfer to Chelsea made my dreams come true. That was the best thing that ever happened to me.

"Maybe I could achieve more and I could have been more successful at Stamford Bridge, but I don't regret anything."
