La Liga is working to restart its competition on 12 June but has not yet gotten the green light from the Spanish authorities.
Meanwhile The Bundesliga is scheduled to continue with six matches on Saturday, the first European elite league to return to action and no fans will attend the match.
“Personally I still don’t have an idea in my head that we will play like this [behind closed doors], “Roberto said.
“Now the Bundesliga will start again, I think it will all depend on how it happened there. We’ve played without fans but it’s very strange and difficult.
“It would be strange to play in front of an empty stadium. Football is not the same without fans. We play for ourselves but also for fans, for people in the stadium to enjoy our game. But we know that even though they can’t at the stadium, they will support us from home.
“We will play 100% so our fans at home feel happy in difficult times like that.”
Barca and Real Madrid including among the seven La Liga clubs who still have to wait until at least 25 May to have a group training session because their area has not yet moved to Phase 1 of the four stages that the government announced is gradually lifting the lockout and achieving “new normality” by the end of June.
Spanish clubs follow strict protocols created by La Liga to limit the risk of spreading the virus.
However, Roberto said it had been “very positive” to continue training, even if it was only individual training.
“The first week went very well,” he added. “We all hope to get back to work. I think all my teammates are the same. We have spent so much time at home that we return to the feeling of being with the ball on the field.”
“We still cannot be together because we are divided into groups in different fields and this is a more individual session. I hope this goes well and everyone respects these steps and that we can get through to the next phase and together soon , that’s what we want. “
“We have to arrive to practice in our kit. We can’t enter the dressing room or anything. We only wear our boots and each player comes five minutes after the next so there is no contact. Then each player has their respective roles. So we go there and warm up, always keeping your distance from other players.
“When we finish, it’s the same. We go and change our boots, put on our shoes and go home with the same clothes we wore for training. We have to take a bath at home and the next day, it’s the same again.”
Real Madrid player Casemiro also commented on the return of the Bundesliga on Saturday. Speaking on the club’s in-house television channel, he said: “This is a very important step not only for football but also for the community, to show and teach people that yes we can. I think if we obey the steps we must do, we can too. “
