6. Boubakary Soumare - Leicester City
Last year, it was revealed that Newcastle had made a bid to sign Soumare from Lille. However, the player opted against a move at that time and despite continued interest from St James’s Park, a deal between the Ligue 1 side and Leicester City was struck this summer.

7. Josh King - Watford
King signed for Everton in January, but after failing to impress Carlo Ancelotti, he was allowed to leave Goodison Park this summer. Newcastle have long been linked to the striker but never made a formal approach before he sealed a move to The Hornets. (Photo by Eddie Keogh/Getty Images) Photo: Eddie Keogh
8. Ademola Lookman - Leicester City
After impressing in spells last season at Fulham, it was inevitable that Lookman would be picked up by another Premier League team. Alas, it was Leicester City and not Newcastle that took a punt on the winger. (Photo by Justin Setterfield/Getty Images) Photo: Justin Setterfield
