It was when a perfectly logical question was emailed in to the official Chelsea website that Old Blue Eyes decided it was time to tell the Tale of Two Changing Rooms.

Why, the enquirer asked, has Fabio Borini not been moved into the list of first team player names that link through to their profiles elsewhere on this website? He has after all, the emailer pointed out, made his full debut for Chelsea.

OBE will now use the rest of this blog entry as an attempt to persuade readers it is not merely an oversight.

For the time being the 18-year-old remains in the squad list of reserve team players, although Fabio is undoubtedly making progress with his Carling Cup start and Premier League sub appearance, not to mention the fact that he is away with Italy Under 21s for the first time this weekend (that's Italy by the way, a country not normally short of striking talent).

To have Borini called up to this international level at such a young age and Jeffery Bruma now a regular at 17 in the Under 21s for Holland (again no mean football nation), is reason for us all to have hope for the Academy delivering for Chelsea.

But to answer the first team squad question it needs a brief explanation on some of the organisation of a top-level football club, especially at the training ground.

The first team squad is not just a selection of players who might be asked to play in the forthcoming match, even though 'a squad' will be named to the players before an away trip or a pre-home game hotel stay.

The first team squad proper is a more-or-less fixed group who train together and change together day in, day out.

It is a place in the club for a young player who has come through the Academy to aspire to. He may train with that squad, frequently in some cases, and he may play first team games with them, but he will not be invited to be a permanent member and to move into their changing room at Cobham until the management decide the moment is right.

Though Borini is moving in the correct direction, his time has yet to come.

He still changes with the reserve squad. Their room is just a few yards further down the ground floor corridor in the main building at Cobham, but it is distinct.

The last player to graduate from reserve to first team room was Sam Hutchinson at the start of this season. Michael Mancienne did similar when he came back from Wolves at the beginning of the calendar year, the same time he made his first team debut.

It is a sign too that the player has done enough to be accepted by the other senior players. The coaches will gauge that when they decide to move a player up.

A third distinct squad at Chelsea is the youth team one. The team line-ups for youth and reserve games can make the boundary appear very blurred at times. Just look at the youthful side selected for the reserves last Monday. Such is the nature of development football.

But in Cobham terms the physical division is greater than reserves to first team. The youth squad players are housed in the Academy building - a pitch-length away from the main building. It is a distance of aspiration.

The youth squad still lunch on occasions in the first team canteen (they have their own canteen in the Academy building too). When one of them is needed to join first team training then the call to come across will be made early in the morning.

Whether a developing player is in the youth squad or reserve squad is a call made by the likes of Steve Holland, Dermot Drummy and Neil Bath (reserve, youth and Academy managers respectively). Boys will be promoted when the moment is right (it might be mid-season) in similar fashion to the first-team model. Conor Clifford is an example of a recent promotion, whereas 16-year-old Billy Knott, who is earning reserve team minutes due to good youth displays, remains for now in the Academy building.

So that's how the learning curve is chopped up at Chelsea. It is why you won't yet find Fabio Borini in the illustrious list of first team players. But watch that space!
