Aston Villa captain Stiliyan Petrov has acute leukaemia

Aston Villa captain Stiliyan Petrov has been diagnosed with acute leukaemia, the West Midlands club have announced.

The condition was diagnosed following tests after the Bulgaria international, 32, developed a fever following Saturday's 3-0 defeat at Arsenal.

"He will get from Villa every ounce of love and support that we have, to help bring this to a positive conclusion," Villa said.

WHAT IS LEUKAEMIA?

Leukaemia is cancer of the white blood cells. Symptoms include pale skin, tiredness, breathlessness and susceptibility to infection. Acute leukaemia means the condition progresses aggressively and needs immediate treatment.

On average 2,500 adults are diagnosed with acute leukaemia in the UK each year, according to Leukaemia & Lymphoma Research

It is understood Petrov will begin treatment in London on Monday.

In the meantime the former Celtic midfielder is being seen by medical specialists.

"We expect to learn more about the situation in due course," a club statement continued.

"During this time we ask that Stiliyan's privacy is placed ahead of all inquiries and trust that we will share information as we receive it."

Petrov joined Villa from Celtic for £6.5m in 2006 and has scored 12 goals in 219 appearances.

He played the full 90 minutes at Emirates Stadium on Saturday, his 30th game of the season, but on the bus after the match he reported to a doctor that he felt unwell.

Aston Villa indicated on Wednesday that Petrov was feeling the effects of a virus, but news he was suffering from leukaemia was only confirmed earlier on Friday after medical tests.

Aston Villa manager Alex McLeish said Petrov was feeling "defiant" and was concerned about his loved ones.

"He's a captain, he's a leader, he's a defiant guy and he's fought many battles on the pitch and I'm sure this is another one he'll win," he said.

McLeish added he was unsure whether Petrov would be able to attend Saturday's home clash with Chelsea.

"He's away with the doc today and I'm not sure of the schedule. He's away to see another top specialist as we speak and I guess we'll know more tomorrow."

Of the other Villa players, McLeish added: "They are gutted but galvanised to try to win the game tomorrow for their captain."

Meanwhile a section of Villa fans have cancelled a planned protest before Saturday's game and McLeish called for fans to be "united".

Villa chairman Randy Lerner said on the club's official website  that Petrov was "cherished by many people throughout football."

"Such was his determination to learn English however that he took to working in a friend's burger van as a way to pick up the language and his fortunes turned as O'Neill deployed him in his more familiar central midfield role."

"We are relying on the very decent and experienced people in and around the club for support, guidance and leadership," he said.

Villa chief executive Paul Faulkner added: "I was completely stunned to hear this news about Stiliyan. After our game last weekend we initially thought that he was suffering from a virus and, like the true leader and consummate professional that he is, he had simply played through it."

Jonathan Fear of the Vital Villa website  said: "There is absolute shock amongst the Villa fans, and the outpouring of love and admiration for Stiliyan increases by the minute.

"Villa fans will show that they care about him during tomorrow's game.

"When the chips are down, Villa is a family and Stiliyan is a large part of that."

Celtic manager Neil Lennon, a friend and former team-mate of Petrov, tweeted  he was "absolutely inconsolable".

"He will overcome this like all the other barriers he faced in his life.

"Stiliyan has the heart of a lion and as part of the Celtic family he deserves all our best wishes and support."
