Leicester's under-21s came from 2-0 down with 10 minutes remaining to salvage a draw and then completed the turnaround with a 7-6 penalty shootout win, earning themselves an extra point.
“It's disappointing but it's still a draw," Barton told the Blackpool Gazette.
“Our lads are disappointed because we absolutely battered them. I know we made 10 changes but we told the lads there were opportunities to push hard for the first team. I thought to a man they were excellent.
“They've had a £20m signing on the pitch and a Premier League winner in Danny Simpson.
“But anyone who was here would have seen the difference in class. I'd be very surprised if any of their boys end up playing for the senior team, whereas we've got lots of young lads playing for ours.
“The conduct of some of them is a bit suspect, talking to our players about how much they're earning and stuff like that. It lacks a bit of class.
"In that respect, I think this is a worthwhile experience for them because they've just been outplayed by a team two divisions below.
“They got very lucky with the penalty shootout. I was disappointed we didn't win it because we were better in every single department for 75 to 80 minutes of the game."
