United net keeper
Dundee United have recruited Polish Under-21 international goalkeeper Michal Szromnik.
Szromnik arrives on a three-year contract for an undisclosed fee from Polish League One side Arka Gydnia.
The 21-year-old should offer stiff competition to compatriot Radoslaw Cierzniak - himself still with another year on his deal.
"I see Michal coming in and challenging for the number one jersey immediately," manager Jackie McNamara told BBC Scotland. "He has a lot of experience for someone his age and every aspect of his game has strong foundations."
