By investing sensibly and with a shrewd eye for a clever loan, Steve Bruce managed to 'fillip' the club with his transfer window buys. For example, Stephen Clemence was monitored for a considerable period of time by Mr Bernie Painter, the chief scout, along with various members of the coaching staff.
They knew, at 25-year-old, what they were getting. A young British player who has proved with over 100 first team appearances for Tottenham, that he can cope in the Premiership.
In Jamie Clapham too, who we released from Spurs five years ago and sold to Ipswich, they have bought someone who has shown that he can perform at his level during George Burley's fine spell, which led to them playing in Europe.
The signing of Dugarry gave Birmingham an international player of quality. Not the biggest goalscorer, but he has given a lift to the club with his playing ability.
The chairman and board have run the club very cannily since the appointment of Barry Fry, which was needed to give the club a boost several years ago, before the Trevor Francis regime that they were very faithful to even though they were very unlucky in one or two play-offs.
Birmingham have found that it takes patience to succeed and they have coped well with the strain of surviving in the Premiership and have had a bonus too - the supporters would say it was achieving a double over fierce rivals Aston Villa.
When Tottenham played at St Andrews it was a rather insipid game on a very grey midlands afternoon. This Saturday we have a chance to assert ourselves in this important fixture.
From Birmingham's point of view, two more wins should see them clear - with Leeds being drawn into the melting pot and Bolton still with a hard task on their hands even though they have just beaten ourselves.
If Birmingham stay up we would wish them well next season because they have done their business in a sensible way and have built their club on solid foundations. They have bought largely domestic promise and promise sometimes take patience.
The blend of Savage and Cisse early on in midfield looked as though it would stand them in good stead and since then they have added quality at the back by signing Upson, another young British player to support the likes of the experienced Vickers and young Purse.
One player who has good form this season is Stan Lazaridis on the left hand side, well supported by the likes of Paul Devlin - a graduate from the lower leagues who has been rewarded with a Scottish cap - and young Damien Johnson signed from Blackburn.
Doing well as a club when buying these types of players and moulding them together, I'm sure gives more satisfaction to a manager in Steve Bruce's circumstances than buying big and possibly suffering later.
Birmingham City have shown that if a club is well budgeted and structured, promotion to the Premiership needn't become the burden of purely trying to retain newly-won status.
