Gordon Strachan said: "It's great news. This tour will allow us to have a closer look at Chun Soo and see whether or not he is of Premiership quality."
Strachan had previously stated: " I would like him to come with us to Sweden so that we can have a close look at him.
''He had a good World Cup and he may prove to be Premiership quality. 'We will have a look at him if at all possible and take it from there. There is nothing definite.''
Saints currently have Pahars, Beattie, Ormerod and Davies available up front for next season. Delgado looks to be a dead loss so a bit of extra cover could come in handy. Hyundai are said to be looking for £700 000 for the player.
