The 23-year-old forward, who has scored four times this season for the Sky Bet Championship klubb, was a surprise inclusion in Steve Clarke’s squad for their forthcoming World Cup qualifiers against Moldova and Denmark.
“It’s great for Jacob and I think it shows the progress he has made since he came to the club,” O’Neill, who brought Brown to Stoke from Barnsley i fjor, told City’s official website:
“We bought him as a young player. He was very raw but we saw a lot of things in his game and I think he’s continuing to develop and progress.
“I had a conversation previously with Steve Clarke about him and I knew they had been watching him.
“I think it’s great for him to get involved. Just to be around the squad and to be involved is a positive as he’s never had the experience of being away with an international team before as far as I know.
“It’s two very important games with Scotland in a position to clinch a World Cup play-off so it’s an exciting time for him to get involved.”
