Oxford United chief executive Mark Ashton says hosting Premier League side Swansea is a fantastic FA Cup third-round draw for the League Two leaders.
And Ashton believes the U's winning mentality can help them cause an upset.
Michael Appleton's side are unbeaten in their last nine matches.
"It is great news for the club and great news for the supporters. I think it is always good to get higher league opposition," Ashton told BBC Radio Oxford after Monday's draw.
"I'm sure Michael will want to pit his wits against Premier League opposition and he will be going out to win the game."
Kemar Roofe scored the only goal as Oxford beat National League side Forest Green in the second round to earn their sixth win in seven matches.
Roofe, who has been linked with a move to Newcastle United, has scored 12 goals this term.
Ashton said: "There is real winning culture in this club at the moment. We are where we want to be and everybody is focusing on getting promotion.
"We are in a good place and we want to keep the team winning as often as we can."
