Jahanbakhsh has been playing for Eredivisie side AZ Alkmaar since joining the club from 2015.
Watford, Bournmouth and Celtic had already showed interest in recruiting the winger.
Dutch AZ Alkmaar would consider bids for the 24-year-old, who can play anywhere across the front line and is technically good with both feet, as well as having an eye for both passes and assists.
A former Iranian U-20 and U-23 international, Jahanbakhsh has won 32 caps and scored three goals but played only a peripheral part in his country’s 2014 World Cup campaign, coming on as a sub in all three of Iran’s games.
