The England Under 21 international has found the net six times for the Greek champions in 11 appearances.
The player's agent Gary Porter insists talks are yet to take place and will not get underway until the end of the season at the earliest.
"Matt has really enjoyed himself in Greece, but there has been no talks between both clubs and there will be none until the Premier League season finishes at the earliest," Porter told skysports.com.
"All Matt's focus is on the cup final this weekend."
