Hughes says the Dane will continue to improve as he settles into the Premier League.
“We're all beginning to understand him more as a person as well – he's starting to be more vocal about the place in terms of his leadership, which was one of the big things we noticed when we were trying to recruit him," said Saints boss Hughes.
“It was always mentioned about how he was talking and leading on the field of play.
“When you meet him he's a great personality and well liked within the group.
“He hasn't been here a long time but he's very much integrated into the group.
“I think he's going to get stronger in terms of his leadership on the pitch and I think we'll benefit from that."
