Bartomeu was asked about Barca's extended pursuit of Inter Milan striker Lautaro Martinez.
He said, "Lautaro Martinez? I won't give specific names, but Barça, like many clubs, has less income.
"We suffer from a significant lack of resources and we have to adapt. We must reduce the payroll and respect Financial Fair Play.
"For now, there is no room for new players if others do not leave."
