Michael Owen scored twice as Manchester United eased into the Carling Cup fourth round with a 3-0 victory over Leeds Tuesday.

Afterwards, Owen insisted he would make the most of every opportunity at Old Trafford, as he extended United's unbeaten run in his first start of the season.

"The pressure is on," he said. "You don't get many chances and then when you do, it can be a couple of months before you see a pitch again if you don't perform."

"You have to prove to yourself and everyone else that you can still perform but we are coming to a stage in the season where the games are coming thick and fast and the games get shared around."

Owen was one of 11 changes made by Sir Alex Ferguson for the Leeds clash, as the United manager fielded an unrecognisable side from the one that beat Chelsea 3-1 Sunday.

Michael Carrick partnered debutant Ezekiel Fryers in a makeshift central defence, while Federico Macheda and Mame Biram Diouf provided midfield support for Owen and Dimitar Berbatov.

Owen opened the scoring with a scuffed shot after a bright build-up involving Berbatov and Park Ji-Sung. Owen was on hand to net his second mid-way through the first half before Ryan Giggs made it 3-0 before half-time.

Leeds manager Simon Grayson admitted United's superior squad made the difference.

"There is a big gulf between us. They are where we want to get to and it looked a long way off. But we didn't perform like we can. We wanted to give United a game and we didn't do that."
