Barcelona star Lionel Messi says he feels "fine" after his knee scare in midweek. Messi was stretchered off against Benfica after colliding with visiting goalkeeper Artur Moraes, but there was relief soon after with confirmation that the complaint was no worse than a bruised left knee.

The Argentina international worked in the gym as his Barca team-mates trained outside today, and Messi said he still had a chance of playing at the weekend.

"I feel fine, but I don't know yet if I will be available for Sunday," he said at a promotional event at the Nou Camp today. "I'll see. I am grateful for all the messages of support I have received."

Messi said he was hurt when he struck Moraes, but then tried to score with a curling shot before falling to the ground and clutching his knee.

"I thought it was the last shot I was going to have for a long time," he said. "So I decided to gamble and hit it."

He added: "The truth is I did not think about anything because all I could feel was the pain. But in a moment I thought the worst. When it was shown it was not a severe injury I was calmer."
