Oh, the glamour of professional football, hawking some Thai energy drink as your new training kit sponsor. While other official shirt sponsors have featured on training wear before, this is the first deal in club history signed specifically for just the training kits.
Chelsea Football Club is delighted to announce Carabao as a new principal partner and our new official training wear partner from summer 2016.
The Carabao logo will feature on Chelsea players' and staff adidas training kit from the 2016/17 season at our Cobham headquarters, at press conferences, on tours, as we travel and in the warm-up to friendly and competitive fixtures.
