Newcastle will face the Saudi Pro League champions on Thursday (5pm kick-off GMT) with Eddie Howe bringing a squad of 28 players over to the Gulf state.
The Magpies currently have five players unavailable due to being at the World Cup in Qatar. Kieran Trippier, Callum Wilson, Nick Pope, Fabian Schar and Bruno Guimaraes are all representing their countries.
But in nearby Saudi Arabia, Newcastle have the rest of their senior squad as well as five promising under-21s players.
Discussing their inclusion, Howe told NUFC TV: “We love to train with 20 players so we wanted to get that ideal number. We want to give an opportunity to young players as well and I think those players who are with us are the ones that deserve to be.
“I won’t speak about them individually but they’ve all got qualities and they all offer something for the now and for the future. It will be a brilliant experience for them and hopefully one they remember for the rest of their lives.”
Here is the confirmed Newcastle United squad for the December tour in Saudi Arabia...
