Manchester United ace Cristiano Ronaldo has detailed his spotkick in Sunday's Carling Cup final shootout victory over Tottenham.

Ronaldo had no hesitation in taking a penalty - United's third - even though missed against Chelsea in the Luzhniki Stadium.

And after a brief game of bluff with Tottenham keeper Heurelho Gomes, the Portugal superstar came out on top.

"It's always important to choose a side and put the ball there," he said.

"After Moscow I thought the goalkeeper would think I put it in the same corner but I changed."

The triumph allowed the Old Trafford outfit to pick up their second piece of silverware, having been crowned FIFA Club World Cup champions in December.

In a seemingly unassailable position at the top of the Premier League, talk outside Ferguson's squad is starting to turn to an unprecedented quintuple.

Yet even as confident a character as Ronaldo accepts the mission is fraught with difficulty.

"It is quite hard," he said.

"We have to think game to game. We won this cup now, we are top of the league and still in the Champions League and FA Cup.

"With United there is always an opportunity to win everything but we need to keep our feet on the ground."
