And so on to find the next two pieces in the jig-saw – who may yet form 'Team Glenn' ahead of the derby game on Sunday.
The new gaffer was giving no clues – other than to say that he had already ear-marked a No2 and a coach; that both were young; both currently in work; but both would view a switch to Norfolk as ?a promotion?.
The obvious one was Nigel Pearson, but that seemed to be a no-no.
So ferret around Roeder's previous clubs – be it Newcastle United or West Ham United – and there's one little character that would appear to fit the bill to a 'T'. And, to my recollection, he's no little character, either.
He's one of Tyneside's finest after a certain T-shirt all but ended his Sunderland career – could Lee Clark be the man?
Now 35-years-old and back at St James', word has it that he has been left a virtual spectator by Big Sam as his legendary back-room staff start to run the place.
But if only on the basis of an interview he gave to a junior BBC reporter on Tyneside last season, it looks as if Clark might fit Roeder's description to the letter.
And nor is Allardyce likely to stand in his way if his current reserve team boss decides to swap the banks of his beloved Tyne for the banks of the Wensum.
?Going into coaching has always been something in my mind,? the 35-year-old one-time Fulham skipper told the cub reporter.
?I've always, after training sessions, gone home and thought about the session and what we've done and put the session down on paper.?
It was, he said, something he started way back when he was a teenage player at St James' – with Walker Central Boys Club, the club that unearthed Shola Ameobi. And he has, it seems, picked up a lot in his travels – and through the revolving managerial door at St James'.
?I've got a lot of things I can take from some superb managers that I've had,? Clark said.
?All the way from Willie McFaul who originally signed me, Ossie Ardilles, Kevin Keegan, Kenny Dalglish, Graeme Souness, Paul Bracewell, Jean Tigana and Chris Coleman and obviously coming back and working under Glenn now as a young coach.?
And there is the first sign of a big link – another one followed. The 'he' is Roeder.
?He's given me a fantastic opportunity to take that to another level. I've been very lucky with the managers I've had, they've all been of a high standard and had different qualities and if one day I am lucky enough to become a manager I can tap into some of those things.?
Cue another one – that after completing his UEFA 'A Licence' in June of last year, Roeder, quote, 'made it clear he wanted Clark to have a greater input into the club's fortunes this year'.
?At the start of the season, Glenn said to me to look at the club as a whole and work with the first team, reserves and academy and take individual players and do some one-on-one work and also sometimes I'll work with players in a small group.
?So I'm coaching right across the board.?
