FC Porto chief Pinto da Costa says the club will not enter any negotiations with Chelsea regarding their highly-rated manager Andre Villas-Boas.

The 33-year old guided to Portuguese club to this season's Europa League title and has since emerged as a strong target for Chelsea who recently parted with Carlo Ancelotti.

But da Costa has made it clear that Villas-Boas is going nowhere even if the Blues are happy to meet his buyout clause of £15million.

"I do not expect the exit of Villas-Boas - there is a clause price of 15million euros but I am totally convinced that even if any club came in with the offer, he would reject the proposition," da Costa told Portugal's public service broadcaster PTP.

"Villas-Boas is very committed to Porto and more so after this big season.

"Two days ago he also told me that if no players leave, then he will not even need any new players."
