French football watchdogs have called on Päris Saint-Germain midfieder Idrissa Gueye to say why he was missing from his side's Ligue 1 match at Montpellier during which the players were required to wear a rainbow jersey in support of the LGBTQI+ movement.
Gueye, 32, was fit for the match but withdrew from the squad for what were described as personal reasons.
