(CNN) Liverpool star Mohamed Salah says his teammate on the Egyptian national football team Amr Warda requires "treatment or rehabilitation" after the player was alleged to have sexually harassed a woman on social media.

Warda, who was originally dropped from the Egypt squad for the Africa Cup of Nations in June following the alleged harassment, was reinstated two days later after pressure from the players on the coaches and Egyptian Football Association, Ahmed Shobair, former deputy chairman of the EFA, told CNN.

Warda is alleged to have sent inappropriate messages on Instagram to Merhan Keller, an Egyptian Dubai-based model, who told CNN in a telephone interview that the player became aggressive towards her after she refused to answer him.

When asked by CNN about the allegations against his client, Warda's agent refused to comment on anything to do with the player.

After speaking out about the experience, Keller says she was victim of a social media backlash where she received a number of abusive messages and was unable to leave her home for fear of her safety.
