In addition, the ten best players in the world, including Novak Djokovic, Daniil Medvedev, Rafael Nadal and defending champion Stefanos Tsitsipas are expected, he insisted.
Tsonga, former world No.5 currently 215th after months of physical suffering, will thus participate in his 10th Monegasque tournament where he reached the semi-finals in 2013 and 2016.
Wawrinka, ex-N.3 currently 233rd also due to long physical problems, won in Monte-Carlo in 2014 by beating Roger Federer in the final.
The other two wildcards will be announced later.
