Besiktas are the latest club to enquire about Everton winger Demarai Gray.
The 27-year-old has already been linked with a move away from Goodison Park this summer, with West Ham and Crystal Palace all reportedly interested in the attacker's services.
Now Turkish Super Lig side Besiktas have entered the race as they look to bolster their attacking options ahead of the new season.
Gray played 36 times for the Toffees last campaign, scoring 3 goals as Everton battled at the wrong end of the table.
Everton have so far added Ashley Young on a free transfer and completed a loan deal for Arnaut Danjuma, but Dyche is having to work within budget restraints at the club.
