Besiktas playmaker Oguzhan Ozyakup could still be on his way out of the Istanbul based club this summer despite putting pen-to-paper on a new contract.
Ozyakup signed a new four-year contract with the Black Eagles earlier this week, however, according to the Turkish outlet Fotospor he included an interesting release clause.
Per the source, Ozyakup will be allowed to leave Besiktas for just £10 million if Manchester United, Manchester City, Barcelona, Real Madrid or Juventus table a bid.
Meanwhile, the Turkey international also has a £15 million release clause for any club from Europes top five leagues (Italy, Spain, France, Germany England).
Ozyakup has been linked with a move to Newcastle United in recent months. According to the Turkish outlet Fanatik, the Magpies are prepared to pay £12 million for the Turkey international.
The 25-year-old is no stranger to English football after spending four years at Arsenal prior to his Besiktas move in July 2012.
Ozyakup provided eight assists in 37 appearances for Besiktas this season.
