If we do sign this new goalkeeper that tells me that the club is planning on selling Cillessen, there is no other option. Jaume is a low earner and selling him would barely bring any money to the club, while Cillessen is a high earner and if he has a good Euro with the Netherlands his price might as well reach 15 million euros, with addition of cutting his salary the club is going to gain a lot of money.
I think they are hoping that between Jaume Domenech and Giorgi Mamardashivili one will turn out solid and able to establish himself at the nr.1 keeper.
