Birmingham City boss Gianfraco Zola is delighted with Arsenal loanee Krystian Bielik.
Zola has praised the performance of Bielik on his Birmingham debut.
The defender made his bow at Preston North End on Tuesday.
"In general I would say it was a positive performance from him," Blues boss Zola told the club website. "In the first half he was suffering a bit. He was a little bit exposed. But second half he was good, so overall a positive.
"Krystian has been impressive in training for us and showed his qualities - he deserved an opportunity."
