Dick Advocaat has backed South Korea striker Ahn Jung-hwan to be a big success if he does ultimately join Hearts.
The former Rangers manager is now South Korea coach and has first-hand experience of the hit-man's quality.
Hearts are looking to push through a £500,000 for the MSV Duisburg star and Advocaat is convinced he has all the attributes to succeed in the SPL.
"I have heard about Hearts' interest in Ahn and that doesn't surprise me," he stated.
"He has proved to be a top international player over the years and having monitored him now for many months I rate him as a very good player. Ahn is 30 now but still fit and strong.
"He is deadly in and around the box and has the knack of scoring goals out of nothing.
"Although he isn't tall he is very good in the air and just as comfortable with his left foot as his right foot when it comes to shooting.
"I did not know him when I was at Rangers but if I had I would have signed him - he is definitely that good.
"He has played in France, Italy and Germany and I have no doubt he would be ideal for the Scottish game.
"Of course he would be able to handle the physical side of things here.
"With all respect, if he is playing for the South Korean national side and has scored goals against Italy the USA, who have very good defenders, then he can do an excellent job for Hearts."
