The striker scored against Saint-Etienne and Sevilla and could cement Gabbiadini’s spot in the starting XI ahead of Charlie Austin (£6.5m).
Gabbiadini was quick to make an impact after signing from Napoli in January.
He scored six times in his first four appearances in all competitions, including a brace against Manchester United in the EFL Cup final.
The goals dried up after he was injured against Tottenham Hotspur in Gameweek 29.
But Gabbiadini may become a key man for new manager Mauricio Pellegrino.
When on the pitch last season, he scored or assisted 71.4% of Southampton's goals.
He also averaged a shot every 25 minutes, only marginally slower than the rate of 22.9 minutes by Harry Kane (£12.5m).
Southampton's opening schedule gives Gabbiadini the opportunity to make a flying start.
According to the Fixture Difficulty Rankings (FDR), only one of their first 11 opponents score more than two.
Gabbiadini is found in just 4.7% of squads, but that figure will soar should he extend his summer goalscoring spree in Saturday’s opener at home to Swansea City.
