Bill Belichick has described the New England Patriots' practices with the Philadelphia Eagles as a "great opportunity".
The AFC East champions moved their training camp to Philadelphia ahead of their pre-season game against the Eagles on Friday.
The Patriots head coach told reporters: "It's nice to be here in Philadelphia, it's really a great opportunity for us to come down here and work with the Eagles.
"I think it will be a good experience for our team to get to see some different people, different scheme. We'll see some different match-ups.
"It will be great for us from a coaching standpoint because we'll certainly have to make some adjustments during practices and as we go. This has been an outstanding organisation through the years, and I'm sure that [Eagles head coach] Chip [Kelly] will have them in a very competitive situation next year."
The Patriots also face the Tampa Bay Buccaneers, the Detroit Lions and the New York Giants ahead of the start of the 2013 NFL season.
