Chelsea have reportedly agreed a £38m deal for Porto striker Hulk.
The 25-year-old has been heavily linked with a move to the Champions League winners in recent months.
However, a release clause thought to be worth around £80m was rumoured to be a stumbling in block for any potential deal.
The Blues have now pushed the Portuguese club down to £38m after discovering that the clause was £48m, according to The Guardian.
The Stamford Bridge side recently started their summer transfer dealings with a move for Eden Hazard.
