Porto president Pinta da Costa is convinced Andre Villas-Boas would reject any approach from managerless Chelsea - despite the highly-rated coach having a release clause of just 15million euros (£13m).
Villas-Boas, 33, would be no stranger to Stamford Bridge, having worked there under Jose Mourinho but, despite the Portuguese coach having seen his stock rise after guiding the Dragons to domestic and Europa League success, president Da Costa sees no reason for concern over his future.
Speaking to Portugal's public service broadcaster PTP, Da Costa said: "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. Villas-Boas is very committed to Porto and more so after this big season."
He added: "Two days ago he also told me that if no players leave, then he will not even need any new players."
While Guus Hiddink is said to be Blues owner Roman Abramovich's first choice to replace Carlo Ancelotti, who was sacked on Sunday, convincing the Dutchman to leave his current post with the Turkish Football Federation could prove complicated.
Hiddink is contracted to Turkey until the end of the Euro 2012 campaign, which could come as soon as October were they to fail to qualify for next summer's tournament.
It has been suggested former Liverpool and Inter Milan boss Rafael Benitez might fancy a stint at international management, which would then pave the way for Hiddink to return to Stamford Bridge.
However, the Spaniard's agent Manuel Garcia Quilon rejected any such speculation. "He has not been approached by Turkey and hence, he has not held talks regarding coaching the national team," Quilon said.
"He has received some offers from several clubs and his priority is to remain in England."
As well as Marco van Basten, former Chelsea midfielder Didier Deschamps is another said to be on Abramovich's radar, having achieved some success at Marseille.
