Tottenham boss Juande Ramos was delighted with the performance of youngster Jamie O'Hara in their 3-0 victory over Derby County.

It was comfortable in the end for Spurs but it did not look like being that way until captain Robbie Keane put his side ahead midway through the second-half, just 10 minutes after Dimitar Berbatov's 58th-minute introduction.

The Bulgarian's arrival, coupled with Ramos' half-time switch that saw Jamie O'Hara replace Kevin-Prince Boateng, seemed to swing the game in the favour of the north Londoners.

It was another substitute, Younes Kaboul, that doubled Derby's misery with a fine finish in the 81st minute before Berbatov added gloss to the scoreline with an injury-time penalty after Alan Stubbs was adjudged to have handles Steed Malbranque's cross.

On O'Hara, Ramos said: "I think it was a bit 'hurry-scurry' in the first half.

"We needed someone like Jamie to put his foot on the ball and slow the game down and get hold of the ball and pass it a little bit more. I think that brought a little bit more order to the game and I think he did that very well. Football games last for 90 minutes so I think you must look at the overall picture.

"I think that Derby worked so hard for the first hour that the effort they used started to tell in the last 30 minutes and that is where we were able to make use of it."

It was only Tottenham's second league win away from White Hart Lane this season, and Ramos is at a loss to explain his side's poor away results.

"From what I have seen while I have been here, the team is certainly working as hard just as much as they are at home. The way we play the game is the same too, I can't see any difference between home and away."

Derby manager Paul Jewell also hailed the influence of Berbatov.

Jewell was pleased with the way the game was going until Spurs took the lead, but was forced to admit that his side just could not compete with the strength in depth of Spurs.

"I think my team might have looked a lot better if I had been able to bring Berbatov on as well," said Jewell. "But we know all about him, he is a world class player. But their silky football was nowhere to be seen for an hour, and I don't mean that to be disrespectful to Tottenham.

"I think we competed very well, but they are better footballers than us. Technically they are better than us. For the first hour I think we had them rattled but once the first goal goes in they look like a different team - and so did we.

"They have a wealth of talent on the bench too. That is why we are bottom of the league, because we can't compete at the level Tottenham are at right now as far as looking for players is concerned and ability.

"But hopefully in a few years, with the help of the takeover, we will be able to because I believe this club is big enough. We might have to take a step backwards to go forward, but I believe we will be able to compete."
