Juventus GM Beppe Marotta says their transfer plans are not over.
Marotta insists the board is happy with their business so far this summer.
He said: "I can confirm that there are two priorities: a left-back and a right winger. The others are linked to parallel operations.
"It's no longer the time to spend crazy amounts of money. Purchasing power must be equal to turnover and besides the Messis and Cristiano Ronaldos aren't accessible to Italian clubs.
"After a disappointing season, it was fundamental to restore enthusiasm to the fans. Our work has only just begun, but they have learnt to trust us."
Marotta then responded to criticism that Juventus' signings have so far been relatively lacklustre.
"We only have to look back at Juventus' history to erase certain prejudices: champions uncovered at little clubs who became great in Turin wrote it. Anastasi and Gentile came to light at Varese, Prandelli and Cabrini at Cremonese and Atalanta, Conte came through at Lecce and Ravanelli had surprised at Reggiana.
"We want to refresh that tradition again."
