Chelsea are the favourites to sign midfielder Arthur Avom from French side Lorient this summer.
Avom, a Cameroon international, has been compared to former Manchester City great Yaya Toure due to his style of play.
According to The Sun, Chelsea are one of three Premier League clubs to have sent scouts to Lorient games this season.
West Ham and Aston Villa also appear to be monitoring his situation but Chelsea are expected to be the 20-year-old's most likely destination.
Lorient, currently top of Ligue 2 with promotion secured, are thought to be keen to tie Avom down with a contract extension.
