It was only 16 months ago that Gary Rowett was handing over the Burton Albion reins to Jimmy Floyd Hasselbaink.
Rowett was taking over a Birmingham City side 23rd in the Championship - and one which had just lost 8-0 at home to Bournemouth - with Hasselbaink hoping to continue his predecessor's fine work with the League Two Brewers.
Since then, the pair have enjoyed almost constant success, with Rowett guiding the Blues to within three points of the Championship play-offs and Hasselbaink now in charge of Queens Park Rangers, having led Burton to not only promotion but to the top of League One.
The Dutchman is still getting to grips with his new club, whom he joined in early December, after they struggled to re-adapt to life in the Championship following last season's relegation.
But there are plenty of positives to be taken from Tuesday's respectable draw at sixth-placed Sheffield Wednesday, and Hasselbaink will be keen to go one better against another promotion contender when the Blues travel to Loftus Road this Saturday.
Rowett, meanwhile, has been speaking highly of his R's counterpart in the Birmingham Mail.
“After I left Burton I had a good conversation with him and I tried to help whenever he has asked,” the 41-year-old revealed.
“He hadn’t asked me an awful lot to be fair. He is an excellent manager in his own right and did a brilliant job at Burton - one we could only have dreamed kept going so well.
“I gave him a little bit of an overview of the squad and an idea of what I thought we needed.
“He inherited a very competitive squad and quite a good schedule as well in terms of the way we did things.
“I know he kept that consistently through. [Burton manager] Nigel Clough has also kept consistent what Jimmy’s done because if something is fairly successful it’s a matter of keeping it going.
“I have had a couple of conversations with him, he’s a really likeable guy, a really effervescent character with some great ideas in the things he has done.
“I still speak to some of the staff at Burton and some of the stuff they were doing before he left was really, really good.
“I hope he turns the QPR situation around.”
