German legend Lothar Matthaus admits he's a big fan of Tottenham attacker Heung-min Son.
Son will be key for Spurs in tonight's Champions League clash with Borussia Dortmund.
Matthaus wrote for The Sun: "In Germany we all saw that Heung-min Son was a decent player in his time at Leverkusen. It is clear, though, that he is a better player, a more consistent and confident one, now.
"When he was in the Bundesliga, he had a lot of chances but missed too many of them.
"For me, I always feel what is important is that a player is getting in the right positions and coming close. If he keeps doing that, the goals will come.
"He has improved at Tottenham, especially the last three years. He has learned and seems calmer when the chances come now.
"You can see his focus is better and so is his finishing."
