Deco says he would love to team up with Portuguese team-mate Cristiano Ronaldo at Camp Nou.
The Barcelona schemer is a big fan of the Manchester United ace.
Ronaldo has enjoyed a fantastic season for the Premiership leaders, but has been linked with a move away from Old Trafford with Barca and Real Madrid both keen to secure his services.
Real attempted to lure the 21-year-old to La Liga last summer but were rebuffed by Sir Alex Ferguson, but Deco would like to see the United star join him at Barca.
"I would like to have Cristiano here in Barcelona," Deco told MaisFutebol.
"He has great talent and is still very young, but it seems unlikely he would leave Manchester in their current position."
With Samuel Eto'o and Lionel Messi both sidelined the midfielder feels Barca are in need of bolstering their squad sooner rather than later.
Deco claims he has been forced to play in some games despite not being fully fit.
