Crystal Palace boss Neil Warnock has made defender Johannes Ertl his third signing of the summer.

Ertl has moved to the Championship club from Austria Vienna for an undisclosed fee on a two-year contract.

He made 50 appearances and scored three goals for the club before he was released at the end of last season.

The 25-year-old can play at centre half or right back and has made eight appearances for the Austrian national side since making his debut in 2006.
