Ondrej Celustka is delighted with his move to Sunderland.
The Trabzonspor wing-back has joined Sunderland on-loan for the season.
"I hope if I play here I will have a big chance to play in the national team," he said.
"This could be a big chance for me.
"I have only played for the Under 21s, I have never played in the senior team, so I'm hoping this move can be good for me.
"Sunderland is a special club with great facilities.
"I have been in Italy and in Turkey but this is a bit special. I have enjoyed playing on the training pitch, it is perfect for what you need to do."
