Alpay told Sky Sports: "I'm really sad because I am leaving my team-mates, and they have been really supportive. But we came to an agreement to end my contract.
"I have strong interest from five other clubs - but I will wait to make a decision until next week."
"This wouldn't have happened if the confrontation had been with any other player than David Beckham.
"The time and effort the English media give to David Beckham is unfair. It is injustice to the other players in the England team.
"The other players work harder than he does. I wanted to leave Aston Villa anyway. I am happy that we have resolved the situation."
