West Ham have joined Everton and a number of other European clubs in the race to sign Chelsea forward Bertrand Traore, according to Foot Mercato.
The 21-year-old has been with the Blues since 2013, but has made just 16 appearances and spent the majority of his time with the club on loan.
The Burkina Faso international spent 18 months with Eredivisie Vitesse Arnhem, scoring 20 goals in 51 appearances.
Last season Traore was on loan with Ajax where he found the net 13 times in all competitions as part of an attacking, youthful side.
Traore has played as both a striker and a winger, and has reportedly attracted interest from Lille, Lyon, Borussia Monchengladbach and Schalke.
Chelsea are believed to be asking for £17.5m having already reportedly turned down a bid of £14m.
Last month, Traore expressed his hope of returning to Chelsea and breaking into Antonio Conte’s first team.
“[Chelsea] is my club,” he said – via the Guardian. “I always dream to play for this club. I enjoyed my games last year and this is my first choice. I want to get some time at Chelsea but I don’t decide it.”
Traore has impressed during his loan spells in Holland, and despite his youth has already played 38 times for the Burkina Faso.
