Neymar was greeted with much fanfare as he arrived in Saudi Arabia on Friday.
The 31-year-old Brazil forward will be unveiled as an Al-Hilal player on Saturday after six seasons with French champions Paris Saint-Germain.
He landed in a Riyadh airport equipped with extra security for the occasion, according to AFP.
Neymar was received in an airport lounge packed with club officials and press, a large diamond-studded cross hanging around his neck as he posed for pictures.
A rock star welcome will await him at the King Fahd International Stadium in Riyadh where he will be unveiled before thousands of fans on Saturday.
Neymar scored 118 goals in 173 matches for PSG, winning five Ligue 1 titles and three French Cups, but his time at PSG was blighted by a catalogue of injuries.
