According to Sky Sports Italia pundit Gianluca Di Marzio, former Watford boss Walter Mazzarri is on the radar of Everton and West Ham.
Mazzarri has been without a job since Watford terminated his contract at the end of last season. Everton boss Ronald Koeman is under immense pressure after the Toffees picked up just several points from their opening several games of the season.
They have also been below par in the Europa League as they were hammered 3-0 by Atalanta before playing out to a frustrating draw with 10-man Apollon Limassol.
West Ham are also keeping an eye out on Mazzarri. Bilic was criticized largely last season as the East London club finished in 11th position on the League standings.
The Hammers have also shown no marked improvement this season as they have lost four out of their several League matches so far.
There is a likelihood that at least one of the clubs will part ways with their managers in the near future and if that happens, Mazzarri will be a serious contender to become manager.
