Antoine Griezmann says Lionel Messi was key to Barcelona's victory over Alaves.

While they won 4-1, Barca were sluggish on the day - until Messi sparked his team into life.

Both Griezmann and Messi struck in Saturday's win and the former remarked: "Messi is the best in the world. We have a great squad and the best player. When the team needs a boost, he appears.

"Now holidays are coming. We can improve, we have not touched our ceiling. It is time to enjoy the holidays and return to continue working and improving.

"I am leaving happy on vacation."
