Rooney, making his first start since ending speculation over his future by signing a new five-year contract, sent Allan McGregor the wrong way from the spot.

The win put United three points clear of Valencia at the top of Group C, with the two teams due to meet at Old Trafford to decide who wins the pool in the final game.

"It took a lot of courage to take the penalty kick," Ferguson said on ITV 1.

"It was not an easy night, he missed a couple of chances but that's what you expect with the rustiness in his game. We are pleased for him."

He added: "Every time he scores a goal he wants to celebrate with the fans and players."

On Rooney's fitness, the Scot added: "He's got a bit to go."

A draw against Valencia would see United top the group.

"We want to go and win the group," added Ferguson. "We've got Valencia at home, we can look forward to that."
