England are ranked number one in the world, and enjoyed a free-flowing opening-night victory over USA on Friday night which extended their winning streak to 28 games - a streak that began nearly three years ago after they lost the final of Rugby World Cup 2021.
The Red Roses are therefore obviously one of the teams to beat at Rugby World Cup 2025, and Bortolami says that in itself will mean other sides will perform at their best when they face John Mitchell's charges.
"They are there because they have very good processes and they all buy into the process to perform and get better," the Italian international said.
"The real challenge is for the players to not get ahead of themselves and for the young players to understand what it takes to stay there.
"The reality is that in sport, at some point it's very likely that you're going to lose a game, but that may be far down the line - especially during the World Cup.
"The challenge of everybody coming after you is a big challenge. You can never lose your attention on the next game. But if you have a fairly mature group I think they can thrive in those situations."
Bortolami has been impressed with the growth of women's rugby that has been seen over the years, and says the expectations on the players to perform on the big stage of this World Cup can only mean good things for the sport.
"I have to say the exposure of women's rugby on TV and in the media has been more and more, and that helps not only those of us who are deeply involved in rugby, but also the other people, the supporters, to get in touch with those venues and those games," he said.
"It's great to see that women's rugby is growing that much. England is a special place to play rugby and there's a lot of attention.
"Obviously there's going to be a lot of expectations and a lot of attention, and I think that's great for rugby.
"Since the Women's Six Nations became a regular feature, it has grown a lot in Italy. The Italian team has been fairly competitive, in some years even better than the men's.
"I can see that growing and I can see that the quality of the players is getting better and better. Obviously England is leading the way in terms of performance and that's great news for the country that is hosting the World Cup."
Bortolami won 115 caps for Italy during his glittering career, during which he represented his country at three Rugby World Cups, and says it's important for the players at RWC 2025 to enjoy the whole experience of the occasion rather than only focus on what happens on the pitch.
"You are in an environment where there is a full immersion in what you do and the media attention, especially here in England," he said.
"So enjoy the on-field part, but also experience the off-field element, because your memories will be made based on what happens on the field but also how you live off the field.
"A World Cup is very intense and there is a lot of expectations in terms of performance, but all those elements, it means that you can look back ten years down the line and see you truly enjoyed those moments and you tried to be as good as you can be."
