Chelsea are monitoring West Ham United striker Enner Valencia.
The Mail on Sunday says Chelsea are interested in Ecuador international Valencia.
West Ham would be reluctant to part with Valencia, though have a replacement lined up in the eventuality.
If Valencia quits Upton Park the Hammers will be in the market for Everton striker Romelu Lukaku and could afford his £30m fee with wages at around £60,000 a week.
