SWANSEA City FC's chairman has hailed the club's multi- million pound impact on the economy as "fantastic".
A study from the Welsh Economy Research Unit at Cardiff University said the Swans' first season in the Premier League had been worth £58 million to the local economy.
It had also helped to create and secure 400 jobs in Wales — 340 of which were in Swansea. Chairman Huw Jenkins said it was "fantastic" news for the club and for Swansea.
And the news comes just ahead of Swansea City putting together its application to expand the Liberty Stadium, which could see capacity rise to 32,000 from around 20,000.
Mr Jenkins said: "We are looking to submit the planning application by March. That's our objective. I hope that is goes through pretty quickly and we can make a decision about where we can go in the following season and what part of the expansion we do first.
"I am delighted and I hope we can remain in the Premier League."
Speaking about the report, Mr Jenkins said it was great that the club had contributed to the economic success of Swansea and Wales.
He added: "My overall feeling for the club is that it is great for us to be part of any recognition for not only helping Swansea, but Wales as a whole, through promotion to the Premier League.
"We now have tremendous coverage right around the world and there's a new TV deal for next season.
"It's great that the football club can help to promote the area. It's brought everybody together, getting behind the football club and the city.
"Our first and only priority is staying in the Premier League, getting to the point of the business of the promotion and what that brings with it: the added benefits. We must look to stabilise that on and off field.
"We are looking at stadium expansion, which will bring more people into the area, we can grow this over a period, working with the local authority."
Mr Jenkins said as well as being beamed around the world on TV, new signings had brought the Swans a global audience.
