Reports have suggested that the Croatia international has failed to travel with Spurs on the tour of America - something Villas-Boas has alluded to in the Spanish press on Sunday.
Andre Villas-Boas "I think Modric is wrong. He has worsened the situation with what he's doing."
Speaking to AS, he is reported as saying: "I think Modric is wrong. This will go against him. He has worsened the situation with what he's doing and now the chairman (Daniel Levy) is very angry.
"This is also not a good time for Daniel Levy, who is in the USA at the moment, because his wife is ill."
