Chelsea hope to thrash out a deal with Villarreal for Nicolas Jackson this week after agreeing personal terms with the forward.
But they could yet face competition from Tottenham, whose new boss Ange Postecoglou is also hoping to add to his side’s firepower having lost Lucas Moura and on-loan Arnaut Danjuma in the summer.
The Blues have an agreement in principal with Jackson on a four-year contract and are happy to meet the £30million release clause with an upfront offer of around £25million and the rest in add-ons.
