Antonio has made a good start to the season with two goals from his opening three Premier League games, which contributed to West Ham beating Chelsea and Brighton respectively.
However, his future at West Ham has been under the scanner due to suggestions that David Moyes is looking to overhaul the frontline.
West Ham are looking to sign another attacker and several possibilities are being explored by the club.
According to French outlet Foot Mercato, talks are now under way which could see Antonio move to Saudi Arabia.
It has been claimed that Al-Ettifaq are interested in the West Ham forward and he is in contact with the Saudi outfit
He is in the final year of his contract and West Ham are open to letting the 33-year-old forward go.
Steven Gerrard has already signed Jordan Henderson from Liverpool and the Al-Ettifaq manager now has his eyes on getting another Premier League star in Antonio.
They do not have to worry about the Friday transfer deadline as the window closes much later for Saudi Arabian teams.
