Michael Beale has admitted Rabbi Matondo is suffering a "crisis of confidence" but defended the winger over recent Rangers criticism.
The forward - signed from Schalke 04 in the summer - has struggled to nail down a starting spot at Ibrox this season.
Matondo, 22, has played in the Bundesliga, Championship for Stoke and in the Belgian top flight with Cercle Brugge. But so far, he's yet to hit the heights at Rangers.
