The Dutch defender spent much of the summer embroiled in seemingly endless rounds of speculation regarding his future.
A big-money move to Anfield was mooted for long periods, despite Liverpool being forced to distance themselves from the reports at one stage after being accused of an illegal approach.
The deadline eventually passed with no deal being done and Van Dijk insists that he is now “100 per cent” committed to the Saints.
He told the Daily Star: “Firstly, I don't think it's appropriate to comment on anything that happened before.
“But I am giving 100 per cent for the club. I work hard every day, I help my team-mates, I'm positive and I want to win every game.
“I am happy and that's the most important thing so we will just see what happens.”
While “happy” at present, Van Dijk has stopped short of ruling out a future move.
Liverpool have continued to see their defensive frailties highlighted after failing to add over the summer and are considered to still be in need of reinforcements.
That could see interest in Van Dijk rekindled, possibly when the transfer window re-opens in January, however, Southampton have shown that they will not be forced into parting with another top talent.
They have seen the likes of Adam Lallana, Nathaniel Clyne, Dejan Lovren and Sadio Mane lured away to Merseyside in recent times.
Van Dijk could be the next to tread that path, but the 26-year-old will not come cheap having signed a six-year contract with the Saints in May 2016 to push his valuation above the £50 million mark.
