The 26-year-old defender has spoken of his distress at seeing his transfer to Chelsea collapse last summer and is hopeful a similar move will come around againPorto left-back Alvaro Pereira has said that he is looking to leave the club in the summer.
The Uruguay international was close to joining Chelsea last year, but a move failed to materialise as Porto held out for the €30 million listed in the player's release clause.
He insists that he has not yet received any offer, but hopes that the Portuguese champions will facilitate a transfer this time around.
"I have spent three unforgettable years at Porto, I respect my contract and I know that I depend on Porto," he told Ovacion.
"But I think this is the time to make decisions. If an opportunity comes for me to leave, I hope that Porto will understand my situation this time and let me leave."
Questioned about his failed transfer to Chelsea, Pereira conceded that he had set his heart on furthering his career at Stamford Bridge.
"I had the possibility to join Chelsea, but Porto decided that I should stay and I respected it," he added.
"I give everything for Porto. I have not spoken with the club yet, I was focused on winning the league.
"I am calm, but the truth is that, if I stay, I have to play. I will not continue at this club if I do not play."
The 26-year-old defender, who joined Porto from Cluj in 2009 in a €4.5m deal, is contracted to the Estadio do Dragao outfit until 2016.
