Supporters overwhelmingly voted the striker as the winner of the award, following an incredible start to his time at Saints.
Gabbiadini netted three goals in his first two Premier League matches, while he also scored twice in the EFL Cup final, at Wembley, during February.
The forward had been up against a stellar list of names, with Tottenham’s Harry Kane, Everton’s Romelu Lukaku, Manchester City’s Gabriel Jesus, Manchester United’s Henrikh Mkhitaryan and West Brom’s Gareth McAuley all in contention.
Gabbiadini polled a hugely impressive 40 per cent of the vote and will be presented with his award in the coming weeks.
Saints travel to Old Trafford on Monday night knowing that a victory would make a huge difference to their standing in the Premier League 2 table.
“There’s a mixed emotion with the boys,” started Jaïdi.
“It will be a good experience to play at Old Trafford, but obviously the other side of it all is that we need to see a reaction from them.
“There was a little bit of a disappointment not to get three points from our last game against Chelsea, but still a draw gets us one point further forward.”
The reverse fixture of this tie took place at St Mary’s back in August, when Saints marched to a 2-0 victory over United.
Josh Sims and Jack Stephens were the goalscorers that day, whilst five other players in that squad have since been involved with the first team this year.
“A part of our role is that we need to develop players,” continued Jaïdi.
“I think we are pretty good at that. We have kept the consistency of doing it for a couple of years now and that has been the same this season.
“That is what we are all about. Providing these kinds of opportunities for the boys to show their quality and put in great performances for the first team.”
Gabbiadini’s scintillating start, which saw him net five times in his first three Saints games, means he beat James Ward-Prowse, Maya Yoshida and Ryan Bertrand to the award.
“I’m very pleased. It was important for me to make a good start and when it comes from the fans it makes the award even more important,” reflected Gabbiadini.
“I’m pleased I’m scoring goals at the moment because the fans are part of football so they’re very important to me and when the harder times come, we will get through them together.”
And when asked whether he had a particular highlight from the month, which included a brace in the EFL Cup final at Wembley, the Italian international forward could not narrow it down.
He added: It’s impossible to choose one moment or one game. I’ve enjoyed every moment.”
WHICH Premier League stars have played the most passes so far this season?
With only a couple of months of the 2016/17 campaign remaining, the stats are clearer than ever when it comes to identifying the best players in the competition.
When it comes to passing, the most prolific ball-players have come to the fore, with one midfield ace already past the 2,000-pass mark - with only 10 others past the 1,500-mark.
Some big name players from the likes of Chelsea, Liverpool, Manchester United and Manchester City all feature near the top of the list.
