He certainly doesn't chop and change the personnel in his side to the degree that Rafa Benitez does at Liverpool or with the regularity that Claudio Ranieiri once did at Chelsea, but nevertheless Glenn Roeder is turning a bit of a ?Tinkerman? here at Norwich.
And long may it continue if it leads to more results being produced in the manner of recent weeks!
Because you get the feeling that the players are now beginning to look over their shoulders.
Gone are the days when certain individuals were guaranteed a starting place in the team providing that they were fit and available for duty.
The Norwich side used to basically name itself, and most supporters could probably guess the entire composition of the squad on a match-day to within a player or two, whereas nowadays it appears that Roeder has developed a penchant for springing the odd surprise and it isn't quite so straightforward.
After all, who would have thought that with the Canaries sitting at rock bottom in the Championship and especially so in season when goals have been at a premium a fit and available Darren Huckerby would have to settle for a place on the bench?
Yet that was the case at Blackpool.
Likewise with Lee Croft in three of the last four games, Jamie Cureton at Stoke and Jason Shackell against Plymouth in mid-week.
And when the rest of the squad see the likes of those players missing out, it sends out the biggest possible signal from the manger that unless you're produce the goods in training and on a match-day, then it's you that could be next.
Accordingly players somehow manage to find that extra ten percent and standards are lifted ? exactly what the manager wants.
And it's showed recently, hasn't it?
Three wins in the last four matches is not only testament to Roeder's tactical acumen and ability to spot and then be able to bring in the right players to improve the team, but also the competitive spirit he has now started to foster at the club.
It could be all change again tomorrow, but with Darrel Russell and Gary Doherty unavailable due to suspension and Martin Taylor struggling to be fit, changes will unfortunately be forced on the City boss as opposed to him opting to make them this time.
One player who will be desperate for the green light from the manager again tomorrow is Ched Evans, who surely did enough on his full City debut against Plymouth on Tuesday to merit keeping his place in the side?
The youngster played exceptionally well and didn't seem at all fazed performing in front of the biggest crowd that he has experienced in his career so far.
He's quite quick, has a good first touch and is ever willing to work across the line, and as he demonstrated only too clearly after just a couple of minutes in mid-week, he's not bad in front of goal either.
City bump into a side tomorrow that would have been shell-shocked in mid-week after finding themselves three goals down at home to Stoke with less than 20 minutes on the clock.
The Potters obviously continued where they left off against Norwich last Saturday and bombarded the Blades into submission with their ugly brand of direct football, but Bryan Robson has promised the United fans that they will do everything possible to bounce back at Carrow Road tomorrow in order to get their promotion challenge back on track.
Although tomorrow's visitors have puzzling only won one of their last seven home games, the Canaries should take warning from the fact that the Blades have also racked up three successive away wins.
