In a bizarre press conference last night Portugal boss Luiz Felipe Scolari admitted money played a part in his decision to join Chelsea as he only intends to coach for "four or five more years".

The 59-year-old Brazilian, whose side play their final Euro 208 Group A match against eliminated co-hosts Switzerland today, takes up the reins at Stamford Bridge on July 1st and claims the Blues post was simply too good an offer to turn down.

"I'm 59, I'm going to turn 60 very soon (in November)," he said. "I don't want to coach until I'm 70. I want to work for four or five more years and then retire."

He added: "Money did matter but it was not the only reason. You only get an opportunity once so it's take it or leave it."

Scolari also pointed to other opportunities for his family in England as reasons for his choice.

"I've got a family, other possibilities are opened up for me," he said. "I might offer my eldest son or my youngest son the opportunity to come with me and study. Sometimes it is good to change things, it's positive. So I didn't decide on the change only because we couldn't get the sums right."

Scolari insists his decision has not changed his approach to his present job or his relationship with the Portuguese football federation, but revealed he had turned down the chance to sign a new deal after holding talks with his current employers.

"Every decision was taken with the parties involved knowing what happened, namely the president of the Portuguese football federation who looked for assistance with some sponsors," he said.

"He tried to get their help but they didn't give their assistance. We wanted to get a similar proposal but after having done that they told me I was free to negotiate with whomever I wished to negotiate. I negotiated."
