Newcastle United have signed teenager Rosaire Longelo, according to a report.
The Sun claim that the winger has signed a four-year deal at the club after passing a medical.
Longelo, 18, had come up through the ranks at West Ham United's Academy.
United manager Rafa Benitez is looking to add to the club's development squad following a number of departures from the Academy this summer.
Longelo is described by West Ham's official website as a "tricky, pacy wide player, with the ability to play at the back or in the attacking third".
Meanwhile, Newcastle have signed four senior players – Kenedy, Martin Dubravka, Fabian Schar and Ki Sung-yueng – so far in the transfer window.
And a fifth player, Yoshinori Muto, is expected to join United in a £9million deal.
Benitez and his squad are travelling to Portugal this afternoon ahead of tomorrow night's friendly against Porto at the Estadio do Dragao.
