Spartak Moscow midfielder Kim Kallstrom has told Arsenal fans to keep an eye on Kristoffer Olsson.

Kallstrom saw the young Swede up close during his loan spell with the Gunners.

"A good player, he has a bright future, indeed. He is well educated, has good technique and has done well at Arsenal.

"It is always hard to move up into the first team, but he is very talented and has done well in the U21s when I played there," Kallstrom told fotbolldirekt.se.
