Ndidi, Iheanacho and Musa were given extended breaks after the Super Eagles of Nigeria crashed out of the 2018 FIFA World Cup in Russia.
After their vacations, the trio has returned to pre-season with Leicester City ahead of the new season.
Musa shared a short on Instagram of him and Iheanacho dancing alongside Tunisia international Yohan Alouane.
At the World Cup, Ndidi played every minute of Super Eagles games while Iheanacho started two and came off the bench in one of the matches.
Musa also started two games and came off the bench in one of them.
Ndidi will be heading into the new season hoping to continue his impressive performances for Leicester City since he joined them in the Winter Transfer window of 2016 while Iheanacho’s aim will be to get regular berth after struggling for game time last season.
Musa was unable to get game time at Leicester City last season and left in the Winter Transfer window of 2018 to CSKA Moscow.
