West Ham were beaten 1-0 by the Saints on Saturday, and they struggled to break down Ronald Koeman’s side’s back-line, even after Victor Wanyama was sent off.
Southampton were resolute throughout the contest, but Gale felt that West Ham’s creative players needed to offer their side more.
"With the man advantage in the second half they didn't really create many chances,” Gale said. “Slaven Bilic's flair players in Enner Valencia and Dimitri Payet were off form. Emmanuel Emenike came on late in the game but he didn't really show much on his first outing for the club.”
Payet and Valencia have been two of West Ham’s main attacking outlets in recent weeks, but they did not show their usual class at St. Mary’s.
Breaking down Southampton has proved to be a tough task for a number of teams of late, with Koeman’s side now keeping five clean sheets in a row.
The south coast side’s victory over West Ham has also reduced the gap between the two teams.
West Ham are only two points clear of the Saints now, and Slaven Bilic's side look set to have to have to fight to hold on to their place in the top six over the coming weeks.
