Brazil have been using Tottenham's training ground as their base ahead of flying out to Russian Federation - via their stop-off in Austria - and Real Madrid defender Marcelo also spoke to the press on Thursday afternoon.
Manchester United-bound midfielder Fred has been ruled out of Brazil's pre-World Cup friendly against Austria on Sunday because of an ankle injury.
"It all depends on the answer tomorrow", Lasmar said at a press conference.
The midfielder is set to join Manchester United after the Premier League club agreed a deal with Shakhtar Donetsk.
"He has had an ankle trauma, but it is still too early for any evaluation, he has already begun the recovery work, he had that part in real pain".
But Brazil manager Tite expects Fred to be fine to resume training with the national side ahead to the World Cup.
It makes sense for Brazil to rest the 25-year-old and not cause any further damage for the midfield star as their World Cup campaign kicks off on June 17 against Switzerland in Rostov.
The five-time winners play further Group E matches against Costa Rica and Serbia in Russian Federation. Prior to their departure for Russian Federation, they will also play a friendly with Austria in Vienna.
