The Blues attempted to lure the Uruguay international, who is under contract until 2016, to Stamford Bridge last summer but their bid was rejected by the Portuguese outfit
The Blues attempted to sign the Uruguay international, who has a buy-out clause of €30 million, last summer but their attempts to land him were ultimately rebuffed by the Portuguese champions.
However, speculation is rife that the Premier League side will revisit their pursuit of Pereira this summer, and the player's representative claims a fresh approach would be well-received.
"Chelsea are the European champions," agent Flavio Perchmen told TSF. "They are a great club for any player, not just Alvaro Pereira. They are a top 10 club in Europe.
"If there is a good offer, we will study it. We want the best solution for his career. We are open to offers, but it has to be from a club of the same level of Porto or better.
"We will see what happens. What he wants is to play."
Pereira, who joined Porto from Romanian outfit CFR Cluj three years ago, signed a new contract with Vitor Pereira's men in December which ties him to the Dragao until 2016.
