Eduardo has promised not to celebrate if he scores tonight after admitting it was the hardest decision of his career to leave Arsenal.
Croatian international Edurado, who had three years at Arsenal, left for Shakhtar Donetsk for £6m in the summer after his horrific leg break hampered his career in England.
But Eduardo returns to the Emirates for the first time tonight with Shakhtar and says he still has huge respect for Arsenal, the fans and Arsene Wenger.
Eduardo said: "I don't think I will celebrate. I respect the club. I had some great moments here and have respect for the supporters and Mr Wenger, for the club.
