American millionaire John Jay Moores in talks with Swansea City.
The 70-year-old Moores previously owned the San Diego Padres Major League Baseball franchise in California but sold the team for $800million in 2012 and it is understood the Texan is in negotiations about taking an equity stake in a club currently sixth in the Premier League.
"You get money for staying in the league but to take that next step you need extra investment and it's only going to get more," Monk said.
"The bigger clubs are going to stretch away with more money and the clubs that are left behind must try to stay on their heels enough to compete.
"This is a way of doing it and that's what the club is looking at.
"Of course I can understand the fans' concerns but Huw and the board are very shrewd in what they do.
"That will never change and I'm sure if someone ever comes in they will follow the line of what's been done before and that the control element will always be the structure we've had.
"So I don't think it's a worry for anyone."
