Cesar Azpilicueta criticised the financial disparity in La Liga which allows Real Madrid and Barcelona to dominate Spain's domestic competition.
The Chelsea defender began his career with Osasuna before moving on to Marseille and Stamford Bridge so has first-hand experience of battling Spain's big two.
However, he told Revista that, since he has left his homeland, the distribution of television money has been a key factor in elevating Real and Barca out of the striking distance of La Liga's smaller clubs.
"The way it is going now with the economic problems in La Liga the gap is going to increase [between Real, Barca and the others]," he told Guillem Balague.
"The little teams have always less money to buy, less television [money] and the bigger teams every year have the best team, the best players.
"It's getting difficult to get closer to them but we've seen this year Atletico fighting for second place with Real Madrid and Real Sociedad is fourth. So teams are always doing the right things and fighting for other objectives."
Balague agrees the uneven distribution of television money makes life difficult for clubs other than Real and Barca - but says there is little hope of circumstances changing any time soon.
"If you look at the difference between the top and the bottom [clubs] it is 6.5 euro per one euro," he said. "It's not going to get equal. It could get to 5:1 but it will just be hiding the real problems.
And Balague suggested a desire for a European-wide league may be at the root of the problem.
"Some people say they are not interested about the domestic league - they want a European league with more public, more money more sponsors, so Barcelona and Real Madrid get even more money.
"That's what I think anyway."
