The Reds began the encounter in positive fashion, pressing the visitors high up the pitch and recording as many as nine shots during the opening 45 minutes – the most recorded at Anfield this season.
It took some time coming, but the deadlock was broken in the 77th minute as substitute Christian Benteke rose highest to meet a James Milner cross and superbly plant a header in the top corner.
Boss Jurgen Klopp celebrated vigorously, however his joy was short-lived as Sadio Mane found a late equaliser before inexplicably getting himself sent off for two petty bookable offences.
Co-commentating on BBC Radio Five Live, Hartson was impressed with Liverpool in spells but felt that they looked ropey at the back which ultimately led to Saints’ equaliser.
"It was a more open second half and Liverpool had spells where they took charge of the game, but they couldn't quite see the game out,” he explained.
“They looked ropey defensively at times. But overall both managers will probably fairly happy. Klopp will have wanted to the first win, while Ronald Koeman will be probably be happy."
The ramifications of gegenpressing:
Gegenpressing, or commonly known as high-pressing in English, has been one of the features of Jurgen Klopp’s managerial career and you can already see how he’s implementing that style at Liverpool.
However, there are obvious repercussions of going full throttle for long periods of time.
Aside from tiredness, if the Reds don’t score early then the intensity level will naturally fade as the game wears on and it could lead to plenty of open spaces in the latter stages.
While Southampton’s equaliser wasn’t as a direct result of Liverpool’s tiredness, the hosts were no doubt feeling the effects late on and there were gaps to exploit especially in behind the Reds’ fullbacks.
