Porto's Andre Villas-Boas looks set to join Chelsea football club following the sacking 解雇 of Carlo Ancelotti in May.

The 33-year-old coach 教練 guided Porto to the Europa League title last season. Porto also clinched 拿到了a domestic double under Villas-Boas last season, winning the league and the league cup.

However, the deal is not signed yet as he has a clause in his contract 他合同里的一項條款 that only allows him to leave Porto should another club offer ￡13.2m for his services. The club says they had yet to receive an offer that activated the release clause.

In a statement it said "so far this club has not received any communication 通知 that this clause has been exercised, nor of the agreement of the coach that is desired."

But, Porto president Pinto da Costa said the club could not prevent Villas-Boas leaving should certain financial conditions 經濟條件 be met.

"Villas-Boas has a contract and a clause of 15m euros," he confirmed. "If someone deposits 15m euros into our account and he wants to go, we cannot do anything because it is something that is contractually specified 合約規定的。"

Villas-Boas, who speaks fluent English, was a scout 球探 for Mourinho at both Chelsea and at Inter Milan. He also worked with Sir Bobby Robson during the former England manager's spell in charge of Porto.

Numerous candidates 很多候選人 have been touted as possible replacements for Ancelotti after a season without any silverware 獎杯. Among them are Turkey boss Hiddink, Villas-Boas and former Fulham, Manchester City and Blackburn Rovers boss Mark Hughes.

It does seem Villas-Boas has a winning streak 連贏紀錄 as Porto ended last season unbeaten in the league with 27 wins in 30 matches, becoming only the second Portuguese club to finish a league season unbeaten, after Benfica in 1972-73.
