West Ham United are locked in negotiations for another Brazilian this summer.
The Hammers failed to secure centre back Fabricio Bruno from Flamengo after agreeing a fee.
The defender turned down the club, but they are moving on to other deals at the moment.
Fabrizio Romano claims that Luis Guilherme could be set to sign from Palmeiras.
The winger is wanted by several clubs, including Liverpool and Chelsea, but may favor this move to get regular football in the Premier League.
West Ham are still negotiating the fee for Guilherme, which they believe will be in the region of 30 million.
