Everton have reportedly placed an £80m price tag on Brazilian forward Richarlison's head amid interest from a number of clubs across the continent.
The 21-year-old has impressed in an otherwise disappointing campaign for the Toffees by scoring 11 times in 28 appearances, while also netting three times for Brazil's senior side in his first six caps.
Everton raised eyebrows when paying Watford £40m to sign Richarlison last summer, but the Toffees believe that his valuation has now doubled after six months on Merseyside.
The Daily Star reports that Chelsea, Paris Saint-Germain, Atletico Madrid and AC Milan have all been keeping tabs on the former Fluminense youngster, but Everton will not sell unless their asking price is met in full.
Richarlison is understood to be happy at Everton, but that may change should under-fire boss Marco Silva - who brought him to English football with Watford in 2017 - be sacked in the coming months.
