Manchester United, Liverpool, Arsenal and Newcastle United have all been linked with Benfica forward Darwin Nunez. RB Leipzig forward Christopher Nkunku is interesting many of Europe’s top teams as well.
Eddie Howe’s Magpies could be big players in the market this summer with their new riches, having avoided relegation. They are in talks to sign Stade de Reims striker Hugo Ekitike.
