England attracted a crowd of 12,000 to their open training session at Twickenham on Friday with Prince Harry among those present.
The Prince, who is a patron of the Rugby Football Union, chatted to coaches and players including captain Dylan Hartley once the hour-long session overseen by Eddie Jones had been completed.
After two rounds of the RBS 6 Nations, the reigning champions are the only team still capable of winning the Grand Slam and their next assignment is against Italy at Twickenham on February 26.
England hinted at the changes they might make against Conor O'Shea's struggling Azzurri midway through the session.
Ben Te'o and Elliot Daly were paired together in a new-look centre partnership, operating outside Owen Farrell at fly-half, with Jonny May positioned on one wing.
James Haskell was restored to the back row at the expense of Jack Clifford with forwards coach Steve Borthwick stating that the Wasps flanker is "playing very well".
Haskell successfully acted as one of Jones 'finishers' against France and Wales but, having now accumulated game time following his long-term lay-off because of toe surgery, he could start against Italy on Saturday week.
The indication from training was that Hartley would retain his place as starting hooker with Jamie George, who was superb in the 21-16 victory over Wales, continuing on the bench.
Anthony Watson's fitness continues to be monitored closely and the Bath wing remains in contention having suffered a hamstring injury in January.
The opposition team at Twickenham wore sky blue bibs to represent Azzurri jerseys, their fly-half also wearing a scrum-cap to mimic Carlo Canna, the playmaker who will pull the strings for Italy.
"It was a brilliant event, seeing the kids enjoy it was fantastic. It's good to give people the chance to come and watch the England team train," Borthwick said.
"Hopefully there were a few youngsters who will be inspired and there are a few here who are destined to play for England, their dads tell me that anyway!
"It's brilliant to have this opportunity to inspire some young children to get into the game."
