Alan Pardew believes keeping Newcastle's first team squad together was more important than securing a number of new players over the summer.
Despite being linked with numerous potential signings, the Magpies struggled to secure the majority of their targets.
Yet Pardew reckons the majority of the club's work had already been completed during the previous summer.
"We did most of our work in the transfer market last summer," he told the Journal. "That was the important period for this football club because it was either going to take us forward or take us backwards.
"Fortunately we made the right selections and it took us forward, and then we have secured them (the top players) as well. You could argue that it was probably better than we might have imagined, so to secure them again was great."
Although the Newcastle boss was pleased to see his key players stay on Tyneside, he did concede that the club faced a fresh challenge to retain those players in January.
"You have to look at six-month segments in this football world now," Pardew said. "It goes from window to window and so from now until January we are stable again, and hopefully we can fend off our rivals or the bigger clubs in the next window so that we get to the next period."
The former West Ham manager was also keen to note the importance the club's senior players have in developing the next generation, believing the squad's youngsters will benefit hugely from working alongside older players.
"I am looking forward to working with the players on the training ground," Pardew added. "It is important for the development of the club seeing that the big players are still here and the younger players can learn off them all the time. When you bring great players into a football club, the beneficiaries are the younger players."
