Wolves have warned Everton off star duo Wayne Hennessey and Sylvan Ebanks-Blake.
Everton boss David Moyes has had Welsh international keeper Hennessey, 21, and 22-year-old striker Ebanks-Blake watched.
But Wolves' chief executive Jez Moxey has vowed that none of the club's big hitters will be leaving this summer.
"We won't lose anyone that we don't want to lose," said Moxey.
