Maya Jama is reportedly being followed on Instagram by Ruben Dias' mother, prompting speculation over a relationship between the Love Island host and the Manchester City star.
During the international break, Jama, 30, flew to Lisbon to watch Dias, 27, play for the Portuguese national team.
She was pictured in the stands last Sunday at the José Alvalade Stadium to witness Portugal's 5-2 victory over Denmark in the second leg of their Nations League quarter-final.
The presenter was seen with a friend and glasses of wine in a VIP hospitality box - usually reserved for friends and family of players.
