"It's my first visit to Bramall Lane and I'm excited for it," Ampadu said. "A lot of people have told me a lot of good things about this place. It's a nice stadium, and I'm looking forward to getting going now. "A lot of people said good things about the manager [Chris Wilder] too, and that came across when I spoke to him myself.
