Chelsea are wrapping up a £20 million deal for Benfica midfielder Ramires this week.
The Sunday Express says Blues boss Carlo Ancelotti wants the defensive midfield player having lost two experienced stars this summer in Joe Cole and Michael Ballack.
Deco is expected to follow - with only Liverpool's Yossi Benayoun coming in.
Ramires, 23, is heading for Stamford Bridge with the deal expected to be finalised in the next few days.
The Brazilian was one of the big successes of his country's World Cup campaign as they reached the quarter-finals in South Africa.
Dunga, who was ousted as coach after Brazil's exit, stressed that Ramires was badly missed after suspension ruled him out of the 2-1 defeat by Netherlands.
Ramires is also wanted by Manchester City, who are ready to outbid Chelsea, but a source said: "He has opted to go to Chelsea, and the deal can be done in the next couple of days, certainly by next week."
