Jose Mourinho has admitted he may be arrested before today's FA Cup final against Manchester United after refusing to reveal the whereabouts of his dog.

Animal-welfare officers have yet to make checks on the Chelsea manager's Yorkshire terrier, Gullit, amid concerns about the animal's quarantine status.

As Mourinho (left) prepared for the first Cup final at the new Wembley Stadium, he spoke of his annoyance at the authorities' behaviour. "Maybe I'll be arrested before the Cup final," he said in an interview for the Portuguese television station TVI. "The dog is on holiday and will stay on holiday while the people are dishonest and while they won't forget that I am a foreigner, a public person, and while they don't treat me as a normal person. I don't want to co-operate. Basically they want to quarantine the dog and only then investigate. I say the dog won't be quarantined. They should investigate and if it is legal it stays with me. If not they can take it wherever they want."

Mourinho, who was arrested and released without charge on Tuesday after police visited his home in London, says he would be willing to provide the authorities with Gullit's relevant paperwork, but would not say where the dog was. "If they want they can see where the dog was bought, the cheque that bought it, all the papers and all the inoculations. And after that they can say, 'Mister, you are right.'

"Nobody knows where it is, only me. And I don't want to say where. When a dog with three months of age is the front page of a newspaper in this country you cannot believe the things you read," he said.

Mourinho's counterpart Alex Ferguson is expected to start with Patrice Evra at left-back rather than Gabriel Heinze. With Gary Neville injured, he must choose between Wes Brown and John O'Shea at right-back.

Chelsea may select Wayne Bridge ahead of Ashley Cole at left-back. Cole has delayed surgery on his ankle until next week in a bid to get himself fit, but he is rated as doubtful by Mourinho.
