The Croatian formally joined Southampton as boss on Saturday but had a watching brief at Fulham due to work permit delays.
Juric witnessed from the stands as Saints secured an important point and their second clean sheet of the season in a 0-0 draw with the Cottagers.
Interim coach Simon Rusk had them playing direct and Ramsdale anticipates they will be more pragmatic under former Roma and Torino boss Juric.
He told BBC Radio Solent: “He spoke this morning, just to say hello and things like that. It’s very clear he is going to try and help us.
"The first thing he said was he wouldn’t come here if he thought it was done and dusted. He will come with an aggressive nature. That is something we can thrive off.

"We have shown we can dig in and keep a clean sheet. When we grow into the shape that we will be playing, we can hurt teams. The boys were outstanding.”
Ramsdale rushed back to the Saints team by playing with a modified glove at Craven Cottage, allowing him to strap his broken finger to another.
The England international's performance was not hindered by the unusual equipment. He made five saves, the best of which to deny Harry Wilson from close range.
“I was really happy with that save," Ramsdale admitted. "Harry is a really good friend of mine. I was on high alert after that in case he put it in the top corner.

“It’s good to be back. I’m probably a bit early in terms of when I should have been. I came to help the team and I didn’t want to miss any more games.
“It was a difficult afternoon. The conditions were windy, this is a difficult place to come. Fulham are a really good team. This came at the end of a difficult week.
“The team have helped. Rusky has been top drawer. I don’t think any of us signed for the football club to play this way. Over future weeks we will play out more but keep the directness.
"We will be more pragmatic than we were today. It’s a great point. We are a point better off than we were at 1pm this afternoon. We are happy.

Juric will be in the dugout officially for the first time when Saints welcome a resurgent West Ham to St Mary's on Boxing Day.
Ramsdale acknowledged The Hammers, who drew 1-1 with Brighton & Hove Albion on Saturday, will pose a difficult challenge.
"We have given the fans something to smile about before Christmas. Boxing Day football is always special. It will be rocking for the manager’s first game.
"We should be full of confidence after the way we defended (against Fulham). Now it’s up to us to nick a few goals."
