Davis Ospina's move to Besiktas may be in doubt, with negotiations stalling, according to Fanatik.
The 27-year-old has told the Istanbul giants that he wants a €3.5 million-a-year contract, but the club are only prepared to offer him €2m.
The goalkeeper has been in outstanding form for his country at the Copa America Centenario, and saved a crucial penalty in the quarter final penalty shoot-out with Peru, helping to book Columbia's place in the semi-finals.
Ospina is almost certain to leave the Emirates this summer in search of regular first team football, having fallen down the pecking order after the arrival of Petr Cech.
