Olsson backs Rams keeper Zetterstrom
Former West Bromwich Albion defender Jonas Olsson believes Derby County goalkeeper Jacob Widell Zetterstrom can establish himself on the international stage.
The 26-year-old has been called up for Sweden and Olsson, who played 25 times for the country, has been impressed with Zetterstrom's progress.
"For a keeper to move abroad, that's something special," Olsson told BBC Radio Derby.
"We don't have a lot of Swedish goalkeepers who play abroad. I think there's like three or four, so obviously the focus on him is greater.
"I think if he continues doing well at Derby, he has every chance to get some game time with Sweden as well."
Olsson added: "What I think stands out as his biggest quality is his decision-making, his intelligence both on and off the field. He reads the game very well and makes good decisions from it.
"What separates defenders and keepers being Championship keepers or defenders from being Premier League keepers or defenders, it comes down a lot to your decision-making, your ability to read the game, your ability to learn from your mistakes.
"I think Jacob has, in every aspect, has got that quality. If you have that quality, and obviously all the other qualities, then I don't think the step from Championship to the Premiership is that great."
