He has since been replaced by Michael Emenalo, the club’s former opposition scout, but manager Carlo Ancelotti raised doubts about his role yesterday when he said the Nigerian would not actually be involved in coaching the first team.

The questions over what happened behind the scenes at Stamford Bridge will now only intensify as Wilkins spoke for the first time since his departure from the club.

“I am very disappointed that the board decided that I had no further contribution to make at Chelsea Football Club which has played such a huge part in my life,” said Wilkins in the statement released by the League Managers Association.

“Since rejoining the club, I am extremely proud to have assisted in Chelsea’s recent successes. I enjoyed a fantastic relationship with the staff, players and the supporters and I now wish them all the very best for the future.

“The LMA’s legal advisors are assisting me in obtaining answers to a number of questions arising from my undoubtedly unfair dismissal, and all efforts are being made to reach an amicable solution. I therefore will be making no further comment at this stage.”

Wilkins returned to Stamford Bridge in September 2008, initially under Luiz Felipe Scolari, and helped the club lift the FA Cup twice as well as claiming the Barclays Premier League crown last season.

His sudden departure raised eyebrows across football as he had enjoyed success not only under Scolari but subsequently with Guus Hiddink and Ancelotti.

Richard Bevan, chief executive of the LMA, said: “Ray’s departure from the club was certainly a surprise given the success that Chelsea enjoyed after his arrival, and the fact that they are reigning Barclays Premier League champions, and currently top this season’s table.

“He has enjoyed an illustrious career to date which began with Chelsea and I share his disappointment and sadness at his leaving the club.”

Wilkins’ statement comes only a day after Ancelotti revealed his own unease at the situation, saying that Emenalo would be assistant first-team coach in name only as he would not actually work with the team during training sessions.

The Chelsea boss made clear that the decisions to remove Wilkins and install Emenalo were not his own.

“I am not here to explain how I feel at the moment, because it is not the right moment,” he said in the Daily Telegraph. “I’m professional, I will continue to work. I want to stay focused on my team.

“The club made this decision (to promote Emenalo) after the decision on Ray. But nothing has changed, for me. Emenalo has been working with me before.

“He started when I came here last year. He was the opposition scout and was supporting me. He’s not been involved in the training, and won’t be, because (first-team coach) Paul Clement has been and will remain doing that.

“But nothing changes. It was not my decision, but he is working with me for a year and a half anyway.”

In announcing Emenalo’s promotion, a Chelsea statement had said Emenalo “will continue to oversee the first team scouting operation as he makes the transition to coaching” as he needed to gain additional qualifications.

But Ancelotti’s comments suggest he does not want any such transition to take place.

When pressed on the matter, Ancelotti reiterated: “He won’t be involved in the training sessions.”

However, Emenalo will sit on the bench for matches, starting today at Birmingham City.
