Chelsea striker Fernando Torres has sparked a row between Nike and club sponsors adidas.

The Daily Mail says Torres' decision to wear a Nike headband against Napoli was in contravention of the club's deal with adidas, who must supply all the kit apart from boots.

Nike say it was not deliberate ambush marketing while adidas said: "We have a contract with the club and are confident they will manage this with the player."

A Chelsea spokesperson said it 'wasn't ideal', and that Torres wouldn't be wearing the headwear again during the adidas contract.
