The Italy international could link up with his Reds team-mates at the weekend when Liverpool head off on their tour of South Asia and Australia.
Balotelli has been linked with a move away from Anfield this summer after he endured a disappointing first season at the Merseyside outfit.
And the 24-year-old appeared in a downbeat and reflective mood as he posted a selfie on his Instagram page on Tuesday night.
Balotelli scored four goals in 26 appearances in all competitions following his £16m move from AC Milan last summer.
The former Manchester City forward has fallen further down the pecking order at Liverpool following the arrival of Roberto Firmino in a £29m deal from Bundesliga outfit Hoffenheim.
The Italian striker managed to score just one goal in the Premier League last season.
