The Uruguay international has been a target for the Blues for some time, with the Premier League outfit first making their interest known last summer.
The presence of former Porto boss Andre Villas-Boas at Stamford Bridge helped to fuel an endless round of rumours, but the London-based outfit remain keen despite a change in the dugout.
Roberto Di Matteo is a fan of Pereira and believes he could be a useful addition to his ranks.
The 26-year-old is very much a modern day full-back and is as comfortable bombing forward as he is defending his own goal.
Porto are fully aware of the reports linking their South American star with a move to England and are due to discuss the matter with Pereira’s representative in the coming days.
“We are due to hold an important meeting with Porto, but I do not want to speculate on what the outcome will be,” Alejandro Savich told Maisfutebol.
Reports in Portugal suggest Pereira could leave on an initial loan deal, with the view to a permanent agreement being struck next summer.
