Nigel Pearson was overjoyed with his players as promotion favourites Leicester launched their season with a 2-0 victory over Peterborough at the King Power Stadium.
Second-half goals from skipper Wes Morgan and substitute Andy King, gave the Foxes the win after a spirited performance from Peterborough in the first-half.
A delighted Pearson said: "It was a good result, and it was a tougher game than people probably expected. Peterborough pass the ball exceptionally well and I'm sure their game plan was to keep it tight, keep possession and get us frustrated."
As the visitors ran out of the steam, the Foxes took charge and a towering header from Morgan in the 50th minute followed by a superb strike from substitute Andy King 25 minutes later, gave them a comfortable victory.
"We pressed higher up the pitch in the second-half and won the ball back in dangerous areas. So, all in all, it was a good day's work and a professional performance," Pearson added.
"It is good to get off to a winning start because we know the expectation on us is going to be there. We all want success here - the owners, players and the fans.
"We all want to do it, but it is going to be hard work for us. It is a very difficult division to get promoted."
Peterborough manager Darren Ferguson believes the Foxes have a good chance of promotion, but he was left frustrated by the result.
"The key appointment for them was giving Nigel the job. He knows the club," he said.
"We dominated the first half but did not create enough chances. The key moment was their first goal. It was a blatant foul. Their centre-half has got both hands on my centre-half."
