Wolves have joined the interest in Porto midfielder Jesus Corona.
The Mexico international's agent revealed contact with Chelsea last week.
However, O Jogo says British sources state Wolves and Everton are in contact with Corona's minders.
Everton see Corona as a replacement for on-loan Monaco wing-back Djibril Sidibe, Wolves boss Nuno is well aware of the midfielder's progress at Porto.
In the current campaign, Corona has already played 44 competitive matches, in which he's scored four goals.
