Luongo completed an inevitable move to a higher division, having contributed six goals and eight assists as Town reached the League One Play-Off Final. Since his arrival from Tottenham Hotspur in 2013, the majority of supporters have expected him to one day make a return to top flight football.
He has come under criticism for his temperament and a consequent dip in his performance level, since his successful appearance for Australia at the Asian Cup, in which he was named Most Valuable Player. Nonetheless, he will prove a significant loss for the Wiltshire-based club.
For Ben Gladwin, who has enjoyed a break-through campaign at the County Ground this season, this switch marks a miraculous rise from non-league football to the second highest division in English football. He thrust himself onto the radar of a string of clubs following eight goals in his last seven appearances.
It is incredible to think that the 22-year-old was was playing for non-league Marlow Town just two years ago. Town fans would have liked to see Gladwin play out another season with the club before moving on, but few will begrudge the youngster of the opportunity to shine at a higher level.
Following a disappointing defeat 4-0 defeat to Preston in the Play-off Final at Wembley last weekend, it is perhaps unsurprising to see the club's star names moving to pastures new. The general consensus around the County Ground inferred that Sunday's match-up would be a make-or-break fixture for the club; a notion that has become reality in recent days.
With Gladwin and Luongo already officially gone, and with several more expected to follow, today could mark the beginning of a difficult summer for the Country Ground faithful. The supporters will placing all their faith in manager Mark Cooper, who will be readying himself for a significant rebuilding project.
Here's how Swindon fans reacted to the duo's departure.
If I was chairman then I'd use the money to pay off our debts and then look at what we can afford next season.#stfc— Ian Mattingley (@MattingleyGrab) May 28, 2015
Not too sad about Mass leaving, because we all knew it was inevitable. #stfc— James Burgoyne (@jburgy_95) May 28, 2015
