Barcelona economic vice-president Javier Faus has conceded that the club could lose Lionel Messi, Neymar or Luis Suárez to richer rivals such as Chelsea and Paris Saint-Germain, according to Sambafoot.com.
The Catalan says that the Blaugrana would be powerless to prevent one of the star trio departing if they wanted to accept the bigger salaries on offer elsewhere.
Faus said: "We can no longer pay the most in terms of wages. That's now Chelsea and PSG. You have to understand that players [in Spain] always compare their net pay to those of the Premier League or the Bundesliga, who have pushed costs up dramatically.
"It will be a challenge but we want to avoid letting Messi, Neymar or Suarez go. But if a club has the potential to take them away because of their chequebook, then they will go. The players have a very short career and are entitled to charge what other clubs can pay for their services."
