Everton are watching Sheffield United fullback Kyle Naughton.
The 20-year-old has already come to the attention of Manchester City and was watched by both clubs on his England Under-21 debut against the Czech Republic on Tuesday.
Blades boss Kevin Blackwell said: "People are becoming more and more aware of Kyle and that includes people from other teams.
"But it doesn't bother us, it's what we'd expect."
