Scope
Chelsea officially announced Pep Chavarría from Rayo Vallecano on 12 August, with a contract running until 2031. The confirmed facts are the player identity, his move from Rayo and the length of the agreement. External coverage may describe the move as part of a changing Chelsea squad, but media counts of summer additions depend on when a source starts counting and which loans or returns it includes.
Method
The working rule is simple: keep the observed result, the calculated comparison and the editorial interpretation in separate layers. The figures below are read against the scope stated in the brief, with matches or player records treated as available only when the source supports them. The unit of comparison is the one named in the brief: a roster entry, a fixture, a player-season line, a transfer record or a dated availability snapshot.
Observations
Separating the transaction from the surrounding tally makes the story more durable. The signing can be stated directly; the number of additions should be labeled as a source-specific count rather than presented as one universal fact. The stable story is a confirmed move and a long contract; the unstable story is every media total built around it.
Limitations
Xtra-Stats does not document the transfer announcement or a canonical order of Chelsea signings, and it has no 2026 statistics for Chavarría at Chelsea. The draft should not add a fee, shirt number or tactical role without a source.
Reproducible takeaway
Run the same check after the next official update and preserve the timestamp. Save the scope and rerun the check when the next verified data point arrives.
A useful follow-up
A reproducible follow-up should retain the same unit, filters and timestamp. If the source adds a row or changes a label, record that change explicitly instead of silently merging two different snapshots.
