Former Chelsea striker looks completely unrecognisable, more than a decade after retirement

Former Chelsea striker Mateja Kezman looks almost unrecognisable, more than a decade after playing his last game of professional football.

The 44-year-old former Serbia international spent time at PSV Eindhoven, Atletico Madrid, Paris Saint-Germain and Fenerbahce during a fascinating, but splintered, career.

He decided to hang up his boots in 2012, aged 33, after a brief spell with Hong Kong First Division side South China.

And now, after serving time as a director of football at Serbian side FK Vojvodina shortly after retirement, he is currently making moves as a sports agent.

In fact, Kezman is currently an agent for Al Hilal midfielder Sergej Milinkovic-Savic, who recently joined the Saudi Pro League side after being linked with a move to England on numerous occasions down the years.

Here are some fairly recent snaps of the former Serbia international.

Kezman is probably best known for his below-par spell at Premier League side Chelsea.

He joined the club in 2004 after scoring 105 goals in 122 games for PSV Eindhoven and, during a time when Jose Mourinho was bringing in a huge amount of talent, there was a real excitement in the air when Kezman arrived in a £5.3 million deal.

The Serbian striker would, however, struggle to find his feet in West London. He would spend just a single season at the club, scoring seven goals in 41 appearances.

Despite failing to light up the Premier League during a forgettable stint, Kezman still recalls his time with the Blues as the best of his career.

"Chelsea was the best thing in my career. That was the climax of my career, for sure," he told Sky Sports.

"Living and playing in London was something that I will never forget. 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."

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