The in-demand keeper had a good season in 2004-5, and as Stoke have 2 quality keepers already on their books, they could sell at the right price.
There has been talk of £1.5m bids for the Everton keeper, but no deal has been done yet.
Boskamp says he'll listen to "big money" offers, but doesn't really want to sell as he feels his squad is already too small.
However, with Ed de Goey signing a new deal and Ben Foster not loaned out yet, Boskamp could afford to cash in on Simonsen.
