Tottenham Hotspur are hoping to raise some transfer funds by selling players who are surplus to requirements.
The club hope that selling both will raise in the region of £30 million. Janssen is not in the manager's plans, as he is not even on the pre-season tour of the United States.
He was on loan at Fenerbahce last season. And the Turkish club would like to sign him, but it is unclear if they can afford a permanent deal.
Llorente is with the club for the USA tour, but he is also on the transfer list.
