Southgate on Tuesday named his first Under-21 squad since taking over the reigns from Stuart Pearce, whose contract was not renewed following the Young Lions' disappointing display at the European Championships.
Pearce presided over a terrible tournament in which England lost all three games and failed to score from open play.
Yet a new-look squad ensured the post-Pearce era began on a positive note two weeks ago when they hammered Scotland 6-0 at Bramall Lane.
Southgate, whose first two games as Under-21 head coach are against Moldova and Finland, was excited by that performance and he is looking forward to helping England's young players make the step up to full international honours just as the likes of Alex Oxlade-Chamberlain, Kyle Walker and Danny Welbeck have done in recent times.
"We had a number of players who did extremely well at Sheffield United," Southgate said.
"We have a lot of exciting players in that age group, it was a terrific performance against Scotland so that's why I haven't made many changes."
Southgate handed maiden call-ups to Tottenham's Zeki Fryers and James Ward-Prowse of Southampton while Wilfried Zaha drops back in to the Under-21s after earning his second full cap against Scotland at Wembley a fortnight ago.
Pearce's chances of success in Israel were hindered by the fact that a number of eligible players did not want to play, or they were selected for England's end of season friendlies against Republic of Ireland and Brazil instead.
England manager Roy Hodgson has often used players from the Under-21s squad in training sessions with the full side at St George's Park, where both teams stay in the same on-site hotel.
Southgate insists, therefore, playing in the youth ranks can be a valuable tool in helping a player's development.
"The clubs have to believe that the players will have a good experience and they will continue to learn when they come to play for us," said Southgate, who returns to management after a four-year sabbatical.
"Much of this process is about helping them get a taste of the senior squad.
"I remember training with Tony Adams and Steve Bould and I learned just as much from them as I did from the coaching staff so they will enjoy this experience."
England kick-off their European Championship qualifying campaign against Moldova in Reading on September 5 before travelling to Finland four days later.
