Rosenior added that the youthfulness of the Chelsea squad is a strength, but that raw talent alone is not enough to deliver success. "They are outstanding and talented players with huge potential and the job for me is to turn that potential into reality," Rosenior stated.
"Having potential is one thing; I'm potentially a very good coach, the players are potentially – although some of them already are – world-class players. But we can't be potentially a world-class team; we need to be a world-class team. That's where I'm trying to take the club."
The new Chelsea boss also spoke highly of Blues skipper Reece James, who Rosenior believes can hit even greater heights in the future. "I've analysed the recent games we've played in and I have to say that Reece, in terms of his impact on the group, in terms of his performances when he's been on the pitch, he's growing every day," the former Hull and Strasbourg boss said.
"It's exciting to be working with Reece at this stage of his career because I think he has levels that he can go even beyond what he's performing now. I think that's where a lot of these players are.
"What I've learned in the last two days, not just about Reece or the leadership group, all the players want success. All of them are honest. They've worked magnificently for me the last two days and I can't wait to get to know them better."
