West Ham have sent a delegation to Portugal to tie up deals for Porto pair Moussa Marega and Yacine Brahimi and Benfica's teenage sensation Joao Felix, as well as set up a working partnership with both clubs, sources have told ESPN FC.
The Hammers have enjoyed a productive summer in the transfer window and they have no signs of stopping as they set up an ambitious raid on some of the best talents in Portugal.
West Ham have brought in seven new faces this season and they want to make further inroads into the transfer market by setting up a long-standing partnership with Porto and Benfica.
