Swansea manager Graham Potter insists he is focused on beating Brentford and not the financial rewards that reaching the quarter-finals of the FA Cup would bring.

Potter's hands have been tied this season with Swansea facing up to the harsh economic realities that accompanies relegation from the Premier League.

Swansea have been in turmoil off the pitch with long-time chairman Huw Jenkins having resigned this month in protest at the way the club is being run by American owners Steve Kaplan and Jason Levien.

No less than 16 players, excluding loan signings, have left Swansea since their seven-year stay in the top flight came to an end and Potter, who was appointed in June, has had to construct an almost entirely new squad.

Making the last eight of the FA Cup for only the fifth time in Swansea's history would provide a much-needed financial boost, but Potter said: "We just want to get through to the next round.

"We can't think about what it might mean financially to the club, or who you might play in the next round.

"You just have to think about Brentford, match what they do and play well against a good team."

Brentford have not reached the quarter-final stage since 1989, when the Bees lost 4-0 to eventual winners Liverpool at Anfield.

"I know all of us want to make a new history," Brentford boss Thomas Frank said ahead of Sunday's all-Championship tie at the Liberty Stadium.

"There's a blank page now, we can go to the quarter-final for the first time in 30 years.

"This is a top, top, opportunity to go to the quarter-final."
