Arsenal have rejected an offer from Fulham for Bernd Leno.
CBS says Fulham have been knocked back with a £10m offer.
The report has claimed that the Gunners are holding out for a fee in the region of £15m.
Leno and Fulham have agreed personal terms on a three-year deal at Craven Cottage.
It has been said that he is frustrated by how talks between the two clubs have stalled.
But despite negotiations being at an impasse, the potential transfer is still expected to go through.
Fulham want to wrap up the deal as quickly as possible to have him ready in time for the Premier League opener against Liverpool on August 6.
