Rafael Nadal said that he was "very pessimistic" over a full resumption of the professional tennis circuit which has been halted by the coronavirus pandemic.
"From my point of view, I'm very pessimistic that the circuit can resume a normal activity," said the world number two in a virtual chat origanized by the Spanish Federation of Tennis (RFET) involving the team that won last year's Davis Cup.
"In tennis, you need to travel every week, stay in hotels, go to different countries," Nadal said.
"Even if it we play without an audience, to organise any event you need a lot of people involved, which cannot be ignored. At an international level I see a serious problem."
Nadal had already told Spanish radio that he thought it would be "difficult" to stage one of the majors "in the short or medium term."
