And trusting his young players is certainly what Ünsal has to do.
As if the duels with Russia were not challenging enough, Turkey have been hit by a series of injuries, ruling many regular players out for the play-offs.
From his initial 18-player squad, Ünsal has lost Asli Iskit, Beyza Irem Türkoglu and Kübra Sarikaya due to injuries.
Especially the absence of 27-year-old left back Iskit, who plays for Thüringer HC, means a blow to the team. Right wing Türkoglu and left wing Sarikaya, both playing for Kastamonu Belediyesi GSK, will also be hard to replace.
Also, experienced centre back Fatma Atalar, who was invited back to the team after four years, got injured in a latest shock to the team, which were already without key players like Yasemin Sahin and Sevilay Imamoglu.
