Port Vale midfielder Doug Loft thinks Vale's summer tour of North America has been one of the main reasons for their impressive start to the season.
Vale won all four matches during the trip in July and have continued their good form in League Two, taking eight points from their first four games.
"It really helped because it was a good bonding session for all of the new boys," Loft told BBC Radio Stoke.
"We've got a tight-knit group here and that's key for the season."
The midfielder continued: "You don't want any divides because it just causes trouble in the dressing room.
"We definitely don't have that. Everyone gets on and we all want the same goal."
Vale, who finished 11th in League Two last season, have won two and drawn two of their four league matches and, along with leaders Crawley, are the joint-top scorers in League Two.
And Loft is confident that Micky Adams's side can build on their unbeaten start to the campaign.
"I think we've got one of the strongest squads in the league," added the former Brighton man. "If you look at our bench, we've got people who could play in any team in this league.
"The boys that have played have done well so they've kept their shirts.
"Everyone will be waiting for their opportunity and when it comes they'll want to take it."
