Berra hasn't represented his country since October 2012, but the former Wolverhampton Wanderers man believes that he is playing well for the Tractor Boys.
The 28-year-old told BBC Radio Suffolk: "I thought that my performances had been quite good.
"It's down to the manager. All I can do is play well for Ipswich and hopefully things will go well from there."
The former Hearts centre-back has scored twice in eight appearances for Ipswich since moving to Portman Road during the summer.
