Everton have signed Lokomotiv Moscow forward Oumar Niasse for a fee of £13.5m. Manager Roberto Martinez wanted greater attacking options after selling Steven Naismith to Norwich and Aiden McGeady going out on loan. Everton’s top target was Dynamo Kiev forward Andriy Yarmolenko but they were frustrated in that pursuit. Senegal striker Niasse has 12 goals in 21 games for his club this season.
