FC Basel defender Eray Comert is attracting Premier League interest.
German media sources say Arsenal are watching the 21 year-old centre-half ahead of the summer market.
Everton are also keen and have sounded out FCB about a price for Comert.
The young defender has a deal to 2020, so this summer represents the best chance for FCB to get top price for his sale.
The Swiss U21 international is rated in the €6m class by FCB.
