Andy Johnson has held crunch talks over his Everton future with manager Dave Moyes.
The People says his heart-to-heart with the boss has alerted Tottenham, Valencia, West Ham and Manchester City, who have been monitoring his situation.
Johnson, 26, has not scored since March and was dropped last week for the UEFA Cup clash against Metalist Kharkiv. He earned a late reprieve when Mikel Arteta was injured, but missed two penalties and failed to register again in Sunday's defeat by Aston Villa.
City boss Sven Goran Eriksson is very keen, having worked with the striker with England. Spurs are also hopeful, although any move would hinge on Martin Jol staying put, while the Hammers had a bid rejected in the summer.
