His agent, Juraj Venglos, expects there to be no development in Weiss's situation until the tournament winds up on July 11.
"On Newcastle, I only know what has been reported. We haven't heard anything, and things will only be decided after the World Cup. I don't know anything until then," Venglos told the Evening Chronicle.
"But Vladimir just wants to play football - and of course he wants to play at a big club.
"He must make the decision himself, though, and that will only come after the World Cup.
"We will see."
