West Bromwich Albion defender Jonas Olsson says Pablo Ibanez will prove his quality at Birmingham City.
The former Atletico Madrid stopper dropped into the Championship last week.
"The English leagues are unique and it takes time to adapt," Olsson told the Birmingham Mail. "I felt that in my first year.
"The leagues are also unique in terms of the tempo and approach to the game, which you really don't have in any other country like this.
"I think there are some really good qualities in Pablo, and I enjoyed the games and training games I played with him."
