Inter Milan boss Jose Mourinho has accused former club Chelsea of making it difficult for him to sign Ricardo Carvalho and Deco.
Mourinho says the Blues have increased the price for the Portuguese duo after discovering his interest in them.
"It's very difficult for a Chelsea player to come to me," Mourinho told a news conference before Saturday's Italian Super Cup against Lazio.
"Every time I'm interested in one of their players, it looks different."
Midfielder Deco and defender Carvalho were part of the Porto team that Mourinho guided to Champions League victory in 2004.
Carvalho was one of Mourinho's first signings during his successful three-year reign at Stamford Bridge, which ended in September 2007 after an apparent breakdown in his relationship with owner Roman Abramovich.
When they know Inter are interested, the price for Deco goes from zero to five (million) and for Carvalho from five to
Inter president Massimo Moratti told La Gazzetta dello Sport in June that talks had begun between the clubs over Carvalho and Deco but these now appear to be stalling, much to Mourinho's frustration.
"In the summer we were told he (Deco) was almost free to come," said Mourinho. "Two weeks later, when they know Inter are interested, it goes zero to five (million) and for Carvalho from five to 15 (million). Something like that."
Deco fell from favour after arriving at Chelsea in an £8m move from Barcelona in the summer of 2008 - and recently admitted he hoped to be reunited with Mourinho in Italy.
And Carvalho, a success at Stamford Bridge but restricted by injury to only 18 appearances last season, has revealed he wants to leave Chelsea after five years.
Mourinho also said Serie A champions Inter had heard nothing from Arsenal or Tottenham Hotspur about midfielder Patrick Vieira, who has been linked with a move to the Gunners - his former club - or their North London rivals.
"If they want him, they have to let us know," he said. "I have to say until this moment, no Tottenham, no Arsenal. They have not contacted us."
