Tadic, a 20-year-old goal-getter, is tipped to move to West Ham by numerous reports in Croatia.
The youngster admits it would be an honour to play for Alan Curbishley's outfit.
"I don't know what to say, I'm very surprised. In a positive way of course," he was quoted as saying in the Croatian press.
"It would be nice to play for the club for which Slaven Bilic and Igor Stimac once played."
