Out-of-date satellite navigation systems are directing fans and players to Swansea's old football ground, the club has said.
People have gone to the old Vetch Field rather than Liberty Stadium
Teams and supporters have ended up at the club's old Vetch Field instead of the new Liberty Stadium - causing one team to almost miss a match.
Bradford City made it just in time to hand in their team sheet after being misdirected by their system.
The problem is caused by the outdated maps in older sat nav devices.
Swansea City played their last game at the city centre Vetch Field at the end of the 2004-5 season before moving to the Liberty Stadium in the Landore area for the 2005-6 season.
David Morgan, director of Swansea City Football said: "We played Bradford City here a couple of weeks ago.
"Their sat nav was taking them to the Vetch Field although they had been to the Liberty Stadium previously.
"Bradford were getting a bit worried - there were phone calls between the stadium and the team coach.
Older sat nav systems have out-of-date information
"Eventually the police had to get involved and they were ready to go out and escort them in," he added.
"They only just made it here in time to hand in the team sheet - they were cutting it very, very short."
Mr Morgan added there had been other occasion where fans had nearly been dropped off at the old ground but the police had managed to get them back on to the coaches and to the Liberty Stadium.
But Ugo Vallario, who organises coaches for Swansea fans travelling to away games, said that most fans would know about the new stadium.
"Clubs coming to Swansea would have had a brochure at the beginning of the season telling them where we are," Mr Vallario said.
The stadium, also the home the Ospreys regional rugby team, is all-seated, with a capacity of 20,280.
