Newcastle United have activated Chelsea winger Christian Atsu's £6.2 million buyout clause after his successful loan spell, sources close to both clubs have told ESPN FC.
Last month, sources told ESPN FC that Newcastle had an option to buy Atsu on a permanent basis included in his season-long deal.
The Championship winners have taken up the option to sign the Ghana international permanently as they prepare for life back in the Premier League.
The 25-year-old had agreed personal terms for a permanent move when he joined Newcastle on loan last summer and is now set to sign a four-year deal.
