Arsenal and Everton are watching North Korean striker Han Kwang-song.

Gunners boss Arsene Wenger and Toffees chief Ronald Koeman have now sent scouts to check on the teenager, who is under contract with Cagliari until 2022.

The 18-year-old international has taken Italian football by storm since becoming his country's first player to appear and score in Serie A five months ago, says The Sun.

Loaned to Perugia this season, Pyongyang-born Han hit a hat-trick in his Serie B debut against Entella last month.

Italian champions Juventus are also monitoring his progress.
