Winger David Cotterill believes the seeds of Wales' good start to their Euro 2016 campaign were sown by former manager, the late Gary Speed.
Substitute Cotterill scored Wales' opening goal in the 2-1 win over Cyprus which maintained their unbeaten start.
The Birmingham City player said Speed, who died in November 2011 aged 42, had instilled a tight-knit team spirit during his time in charge.
"He started all this off, the togetherness," Cotterill said.
"Every time we've come away the last few camps everyone seems together and it definitely changed when Gary Speed took over.
"Chris Coleman's taken that on board as well and things are improving.
"Everyone here is working extremely hard for each other and we're all together."
Real Madrid and Wales forward Gareth Bale said the win over Cyprus in Cardiff showed the "togetherness" in the national squad under Coleman, who took over in January 2012.
Wales failed to reach the 2014 World Cup finals in Coleman's first campaign in charge but have made a good start in the Euro 2016 qualifiers and are top of Group B.
Former Swansea City winger Cotterill replaced the injured Simon Church early in the game against Cyprus and scored Wales' opening goal in the 2-1 win.
Cotterill had been recalled to the squad for the Euro 2016 double header against Bosnia-Hercegovina and Cyprus in Cardiff.
The Cardiff-born player hopes to add to his 21 caps against Belgium in Brussels on 16 November.
"It's always nice to play for Wales and it's nice to be back in the squad," Cotterill said.
"My form for Birmingham has been good and I thank my team-mates who have helped me along the way.
"I always want to play for my country and hopefully [the Cyprus game] will make sure I'm in the next squad.
"We've got a tough next game and hopefully we can get something out of that."
