My Roman friend

Unfortunately for Kezman, Mourinho has been less understanding. Although full of respect for the Portuguese's achievements as a coach, Kezman feels he has never received his full support and never been given an explanation for his repeated omission from the side.

The 26-year-old has started just six Premiership games since his £ 5million move from PSV Eindhoven and was particularly angry to be dropped after contributing significantly to Chelsea's thrilling Champions League win over Barcelona.

There is also the suggestion that Mourinho's ego, his desire to be the best and the most prettiest, overshadows the achievements of his team.

Kezman said: "It's a pity that Jose Mourinho never stood behind me, never gave me full confidence. I can't score a lot of goals if I am only playing for five or 10 minutes. Ole Gunnar Solskjaer can do that. Not me.

"I spoke to Mourinho a lot about my situation, but we both look at it with different eyes. He thinks something, I think something different.

"I have to accept it because Mourinho is the big boss. 'Why?' was the big question for me but there was no answer. I am number two. Everything I do is not good enough. That's the feeling I have and that's very hard to accept.

"I respect him because he has fantastic results. From his side he understands my situation but he cannot change anything. He would be crazy to change it.

"This is the way he works and this is the way he had success the last couple of years. He feels he is the best and he is the most prettiest. You have the world of Mourinho and you have the other world."

Mourinho questioned in a recent interview why Kezman had appeared capable of scoring two goals in every game for Guus Hiddink at PSV but only two in a season under him. The answer is now clear for all to see.

Having arrived at Stamford Bridge as a cocksure young gunslinger, he is now afraid to load his rifle, too scared of missing to shoot for the target.

After shattering the Dutch scoring records by scoring 105 goals in 112 league games for PSV, Kezman has scored just four Premiership goals this season and he had to wait until last month's trip to Norwich to score his first from open play. Whether he likes it or not, Mourinho must accept some responsibility for the player's declining performance.

Kezman said: "Confidence in football is 80 per cent. A player without confidence is worth nothing. In the past I could do anything - a double scissors, a volley, a bicycle kick, everything happened for me.

"Over here I want to show everything but it doesn't happen because there's fear in my head. A one-on-one is difficult because I fear for loss of possession. With a cross for the goal I think maybe it is better to give it somebody else."

For all his fears, Kezman has been brave enough to admit to his shortcomings and is already contemplating a future away from Stamford Bridge. Given his scoring record in Holland, there should be no shortage of offers. Kezman said: "The last few weeks I have been thinking a lot about it. 'Is this for me? Do I want to have fun in football? Is this the price I have to pay to win the big prizes?'

"If I have to play like this, maybe it's better to leave and be on the pitch again with a smile on my face. I have a lot respect for guys like Geremi and Scott Parker but I don't really understand them.

"They hardly play but still they can smile. I am not like that. If I cannot play football I feel bad and then I fight with everybody. I cannot cope with this for very much longer.

"I have learned that having fun on the pitch is the main objective for me, at a club I like in good surroundings. Why not take a pay cut to leave?"

After Mourinho reads his comments, he may have little option.
