The Arsenal loanee has scored in both Blues Championship games so far, and they were excellent finishes.





"I was pleased with Jon, he has an instinct to get into those positions," commented Rowett, after his strike in the 2-2 draw against Burnley.





"And when he gets into goalscoring positions, he has got real composure.





"That's two in two league games now, and that's why we brought him in. We felt we needed a little bit more of a threat in those front areas, in terms of our goal ratio.





"I am really pleased with the way he has started.





"We know we have got a great option in Andrew Shinnie as well, who went very well in the Capital One Cup in the week.





"I think we have got some real competition."





Another of Rowett's new additions, Maikel Kieftenbeld, has also slotted into the groove quickly.





Alongside Stephen Gleeson, the Dutch star has taken to his midfield task with aplomb.





"It's something we looked at last year," explained Rowett, in regard their combination as the two 'sitters' in the 4-2-3-1.





"Sometimes when we have got two good passers in there we seem to get a little more control.





"The way we play, where you intercept, that transition of winning the ball back quickly, then you just need that little bit of coolness to get people into forward areas.





"At times, I thought Maikel and Stephen were really, really good at that."





Rowett continued: "And one thing you have got there, particularly with Maikel - but I thought Stephen did it better on Saturday - is that they quicken up on people, they close them down, they win battles and are strong defensively."





"I am pleased with the way the side is developing. Quite slowly, but we are turning into a really good side," he added.





Blues are next in action at St. Andrew's on Friday against Derby County, who have thrown a lot of resources into trying to fashion a promotion-winning team.





Rowett is looking forward to his side going toe-to-toe with one of the pre-season Championship favourites.





"What I like about us is that without spending lots and lots of money, you look at our team and you see quite a lot of quality.





"Against some of the other Championship sides, you'd expect them to have so much more quality than us.





"But you see some real good attacking options, some real good attacking play, from us.





"We will just keep growing as a team.





"And that's what we have got to be: we have to be as good as any team in the division because we can't necessarily rely on our individuals (alone) like perhaps others can."
