"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."
