Everton have been linked with a £10million bid for the very promising teenage sensation Nikola Vlasic and to further fuel speculation regarding the 19-year-old's potential move to Goodison Park, Kos has admitted that a transfer could be on the cards due to his club's financial situation.
He told Split newspaper Slobodna Dalmacija: "The transfer window runs until August 31, sometimes transfers happen a minute before midnight.
"We don't want to lose one per cent of our quality. We also have to think about financial stability. I don't like to talk about things I cannot say with certainty. We'll keep track of how things are going."
