The striker believes that the owner is already putting the structure in place to make the Owls a top flight club.
Under current manager Carlos Carvalhal, Wednesday lie seventh in the Championship, just two points off the play-off positions. And the Austrian suggested that it was largely down to Chansiri that the club remain in contention for promotion.
"Some things have changed around the stadium and training ground and I think that's credit to the owner. He wants to update things even more and to become a football club who wants to challenge to be in the top division," he told the Star.
After a slow start to the season - where they won just once in their first seven league games - they have recovered to put themselves right in the play-off mix. Their campaign is all the more impressive given that they have also enjoyed an excellent run in the Capital One Cup, where they reached the quarter-finals, having knocked Newcastle and Arsenal out along the way.
And Wednesday fans will be hoping that Chansiri further proves his desire to end the club's long wait for top flight football by backing Carvalhal with funds during the rest of the January window.
