Sport says Barcelona are looking to add a top level centre forward to their squad.
Silva was on Barca's radar a few seasons ago when he was at Sevilla. He has scored 28 goals in 32 games in the Bundesliga. His market value is 45 million euros but Eintracht might sell for as little as 35 million in the current market.
His agent Jorge Mendes is working on a move and Barca are among various clubs he has spoken to.
