Chelsea F.C Jersey Player Version - Blue

Here's a general overview:

Primary Colour: The primary colour of the jersey would be Chelsea blue, which is a rich, royal blue.

Club Crest: The Chelsea F.C. crest would be present on the left chest when worn. The crest features a lion holding a staff, a reference to the club's historical association with the monarchy.

Manufacturer's Logo: As of my last update, Chelsea's kit was made by Nike, and the Nike swoosh logo would be on the right chest when worn. However, the manufacturer could change in future seasons.

Sponsor Logo: As of my last update, the main sponsor logo would be on the centre of the shirt, though this can vary by season.

Design Features: There may be additional design elements, like subtle patterns in the fabric, contrasting trim on the sleeves or collar, or other details.

Player Version Differences: The player version or "authentic" jerseys are typically more fitted and use more advanced fabric technology than replica kits. They might feature ventilation zones for breathability, and the sponsor logos and club crest might be heat-pressed rather than embroidered for a lightweight feel.

Please note that this is a generalized description and the actual design may vary depending on the season and the specific choices made by the club and the kit manufacturer for that year. Always check the official Chelsea F.C. website or official kit supplier for the most accurate and up-to-date description of their current kits.
