Everton boss Carlo Ancelotti has pulled some strings at former club Napoli with a fee reportedly now agreed to bring Allan to Goodison Park. Everton have so far been frustrated in their attempts to sign their top targets this summer.
The Toffees had initially reached an agreement with Southampton to sign Pierre-Emile Hojbjerg.
But Tottenham soon snuck in to steal the midfielder from under the noses of Everton.
Gabriel Magalhaes had also been strongly linked with a move to the blue side of Merseyside, but Arsenal have swooped in to complete a £25million.
Everton have done some business this window, signing Niels Nkounkou after the full-back left Marseille as a free agent.
