Luciano Vietto insists there's no bitterness towards Diego Costa's arrival at Atletico Madrid.

The former Chelsea striker's signing is expected to see Vietto squeezed out in January.

However, the Argentine forward is adamant there's no hard feelings against his new teammate.

"This will be an important reinforcement for the team. He's been there before and he did very well," said Vietto.

"I wish him the best."
