Bongonda, 21, is in just his second season with Celta following a move from Belgian club Zulte-Waregem in 2015. But the ambitious winger already has designs on moving to a bigger club, with the Premier League a possible destination – although a move to Diego Simeone's Atletico Madrid or Sevilla would also interest him.
"I could comfortably stay another two or three years with Vigo, but it is not my ambition to spend the rest of my career with them," Bongonda told reporters, Goal report.
"If Chelsea, Manchester United or Atletico Madrid call me in the near future I should be ready to make the step up to join them.
"Every footballer wants to play at the highest possible level. If I could choose my next club I'd say Sevilla – I've always felt attracted to them although I don't know why.
"They would be a terrific next step in my career. They are always in the top five in La Liga, always in Europe, and Seville is an attractive city."
United are expected to further strengthen their attacking options this summer although manager Jose Mourinho has indicated he has already decided which players the club will attempt to sign.
"In the second season, I know everything that is going on," Mourinho said in March. "I know the players I want, the players I don't want, why a player is playing, why a player is not playing. Now, I am inside for 10 months and 10 months is a long time and the second season is, I think from the managerial point of view, an easier season than the first."
