Nicklas Bendtner's father and agent, Thomas, claims his son is attracting interest from 'all the big leagues'.
The Arsenal striker has regularly expressed his frustration at failing to hold down regular first-team football at the Emirates.
He has hinted that he may be forced to move on in order to get the games he feels he deserves.
That has fuelled speculation that he could be offloaded this summer, with Arsene Wenger keen to tinker with his squad.
German giants Borussia Dortmund and Bayern Munich have been linked with moves for the 23-year-old frontman, while Sporting Lisbon are keen on taking him to Portugal.
Reports in the past have claimed that Italian clubs have contemplated making an approach, so Bendtner has plenty of options to consider.
His father insists no decision regarding his son's future has been taken as yet, but he has confirmed that the race to secure his signature is gathering pace.
"There has been interest from all the big leagues, but there is nothing concrete yet," Thomas Bendtner told Sporten.tv2.dk.
"The window is open for a long time."
