The agent of Alvaro Pereira has slammed Porto for not selling the Uruguay fullback to Chelsea.
The frustration at the breakdown was voiced by one of Pereira's representatives, Flavio Perchman, who was quoted in Portugal suggesting Porto's stance was a legacy of Villas-Boas's defection to Stamford Bridge over the summer.
"Unfortunately, talks have collapsed," said Perchman, an associate of Pereira's agent, Alejandro Savich. "Porto did not honour their word because, last year, they promised to sell Alvaro if an offer upwards of €20m was tabled. Chelsea offered more than that. I think they are trying to use Alvaro to get back at Chelsea about Villas-Boas.
"No-one pays €30m for a full-back - not even Roberto Carlos cost that."
