United agreed to sign Sporting winger Nani, who has been compared to Cristiano Ronaldo, for $35 million and Porto's Brazilian playmaker, Anderson, dubbed the new Ronaldinho, for a similar amount.
The 20-year-old Nani, a left winger, had also been linked with Tottenham Hotspur. He was named in the Portugal squad for Saturday's Euro 2008 qualifier in Belgium.
A broken leg suffered last fall did not deter interest by a host of European clubs in the 19-year-old Anderson, the MVP of the 2005 Under-17 World Cup.
He played the last two seasons for Porto after leaving Gremio and had a brilliant Champions League campaign before his injury in a Portuguese league game against Benfica. He is on the short list for Brazil coach Dunga's squad for the Copa America in Venezuela.
