Uruguayan full-back Alvaro Pereira has revealed his disappointment in seeing his summer move to Chelsea fall through.
The Porto man came close to moving to Stamford Bridge on deadline day in the transfer window, and hopes were rife that a deal could be resurrected in the January transfer window.
However, Pereira signed a new deal with Porto, keeping him at the club until 2016, to all but end the speculation over his future, but the 25-year-old admits he's still upset over how his move to Chelsea fell through.
"I'm still frustrated that my transfer didn't take place," he said.
Reports suggest Pereira's contract at Porto has a £30 million release clause, however Chelsea may be granted permission to speak to the player if he intimates he wishes to leave.
Chelsea have had continued problems at full-back, with Jose Bosingwa's defensive fallibility exposed on a number of occasions, and Branislav Ivanovic's unwillingness to get forward means the addition of Pereira is much sought after.
