Everton chairman Bill Kenwright admits he's been made aware of potential replacements for manager David Moyes.
He admitted he has fielded enquiries about a potential vacancy at Everton this summer as uncertainty over Moyes's future prevails.
Wigan's Roberto Martinez and Celtic's Neil Lennon are among those being linked.
"Does the phone ring? Yes," Kenwright said. "What is my answer (to those enquiring about a potential vacancy)? It is very simple: Everton football club has its manager."
