Stamford Bridge side chase Upton Park forward.
Chelsea have been told to stump up as much as £30m if they want to sign West Ham attacker Enner Valencia according to the Metro.
Jose Mourinho is known to court the Ecuadorian though one wonders if he would be willing to make such a massive offer for the Hammers star.
West Ham paid £12m for Valencia after he had impressed at the 2014 World Cup finals and the speedy forward impressed during his debut campaign.
Mourinho is keen to strengthen his attack with Didier Drogba having left the club and Loic Remy failing to secure anything more than a bit-part role in proceedings at Chelsea.
Valencia can play out wide or in a central striking role and it’s this versatility that could well be the chief reason as to why Mourinho would be keen on the former Pachuca man.
