On Tuesday night, 19-year-old Truls will play in the World Cup final against world setter Fan Zhendong from China.
Möregårdh's final place is described as a sensation in the world of table tennis.
If he were to beat Fan Zhendong there (against all odds), it would have shaken the great power China a lot.
With a few exceptions, China has dominated table tennis for many decades.
But there have been a few challengers - not least from Sweden.
With his six World Cup golds and Olympic gold in 1992, Jan-Owe Waldner won deep respect in China.
So much so that he was nicknamed Cháng Qīng Shù - "The Evergreen Tree".
