Steve Bruce was presented as Newcastle manager, replacing Rafa Benitez.
Bruce said he was out to prove skeptics wrong.
“I know in some people’s eyes, I’m not Rafa and I understand there are big shoes to fill. But believe me, I’ll give it everything I possibly can and hopefully prove the doubters wrong," said Bruce.
Newcastle are also linked with 22-year-old striker Joelinton from Hoffenheim.
