Liverpool striker Luis Suarez has been warned by Adidas that he needs to improve his conduct as long as he wants to remain sponsored by the global sports brand.

The 26-year-old has been fined by the Merseyside club for biting the arm of Chelsea defender Branislav Ivanovic during the Reds' 2-2 draw at Anfield on Sunday.

A statement issued by Adidas said: "We take this type of incident very seriously. We will be reminding [Suarez] of the standards we expect from our players. Luis has admitted his actions were unacceptable and we support the way Liverpool are planning to handle the situation."

Suarez, who apologised for the incident, is expected to be handed a lengthy ban by the Football Association this week.
