Wayne Rooney says that Manchester United's success during his time at the club was driven by the communication they built up while playing video games on the team bus.
On BBC's podcast The Wayne Rooney Show, the former Manchester United, Everton and England forward said he and his teammates played Five-On-Five on the PlayStation Portable game SOCOM.
"I really believe that a lot of our success was because we played PSP," Rooney, who won five Premier League titles and the Champions League under Sir Alex Ferguson, said.
"It made us communicate more - we'd play it on the plane, on the team bus."
It would be me, Rio [Ferdinand], Michael Carrick, John O'Shea, Wes Brown. You had to talk, be tactically correct, go and revive people when they died, and that was a massive part of our success - ask any of those players, it was brilliant."
Rooney even said his teammates' playing style on the video game reflected how they played on the pitch at Old Trafford.
"The way you played that game reflected the player you are, how you play the game," he added. "Michael Carrick was a little cunning, quiet, you'd lie down hidden and you'd hear the little grenade he'd throw."
"I was just all over the place, straight up, in the frontline trenches, go in."
However, it wasn't to everyone's taste, as Dutch goalkeeper Edwin van der Sar would confirm.
"Edwin van der Sar was annoyed because we were on the team bus and you could hear all this shouting on the bus, where you'd tell them where you were," Rooney said.
"Sometimes, if you had one player left, you'd communicate, so you'd flank them, go in and get them. Van der Sar was annoyed and moved, he'd try to get as far away from us as possible!"
West Ham need 'good foundation'
Rooney also spoke about West Ham's problems on his latest podcast, saying the Hammers need a "good foundation" rather than jumping between managers as Graham Potter faces increasing pressure.
After a 2-1 loss to Crystal Palace on Saturday, several BBC Sport sources have said Potter is facing significant internal scrutiny, with the club now considering managerial alternatives.
The 50-year-old was appointed in January - replacing Javi Gracia - but has only won 6 of 25 games, losing 14 and drawing 5.
Nuno Espírito Santo, who was recently sacked by Nottingham Forest, is known to be one of the options to replace Potter, with former boss Slavia Bilic and former Wolves boss Gary O'Neil also in the mix.
If West Ham do change managers, it will be their third appointment since David Moyes left in May.
"It takes time to let players go, bring players in and then, before you know it, this manager isn't getting results and then they go and you're back to square one," Rooney said.
"I think having a good foundation for the club will help."
West Ham have lost four of their five league games this season - only beaten by Nottingham Forest - and exited the League Cup to Wolves.
Only bottom club Wolves have conceded more goals than West Ham's 12, and they are the fifth lowest scorers alongside five others.
The Hammers, who are 19th in the Premier League, return to action on Monday 29 September against Everton, where they will face Moyes again.
"Brighton and Bristol are playing a clear way and that's because the clubs have set managers who are going to come in and they already have their own philosophy, regardless of who the manager they bring in is, they follow it and that's why you see progression with those clubs," Rooney said.
"Slavia Bilic earlier - I know it was a long time ago and maybe talking about his return - has a different philosophy and when you change philosophy to philosophy, which Manchester United did with Erik ten Hag and now Ruben Amorim, it's a completely different way."
