Wrexham came agonisingly close to earning a shock win over the Saints on the opening day of the campaign.
Josh Windass opened the scoring from the penalty spot for the visitors at St Mary’s Stadium but last-gasp goals from Ryan Manning and Jack Stephens earned the hosts victory.
Despite that triumph, the Saints struggled under Will Still and parted company with the head coach in early November.
They have drastically improved under German boss Eckert, winning nine of their past 12 league fixtures.
But Lewis O’Brien, who netted his side’s second goal at West Brom last time out, feels Wrexham’s improvement since the first fixture between the sides is evident.
“We were a pretty new team. There were a lot of signings and we were trying to understand how everyone played,” the midfielder said of the August contest.
“We’ve now got three games at home and three away and hopefully we can pick up as many points as we can.”
