Manchester United manager Sir Alex Ferguson has warned Real Madrid that signing superstars like Cristiano Ronaldo and Kaka could unbalance their team.
The Spanish club paid a world record 80 million pounds fee to sign Ronaldo from United and splashed out 60 million pounds for AC Milan's Brazil playmaker Kaka.
Lyon striker Karim Benzema has also moved to the Bernabeu but Ferguson is unconvinced by Real's decision to sign so many high-profile players.
"There's a very good example of a team in the 1950s, Sunderland, who spent so much money it was known as the Bank of England club. They didn't win anything and in the end they got themselves relegated," Ferguson told The Times.
"I'm not saying Real Madrid will get relegated, but it's difficult and they will have plenty of problems with balance.
"I wouldn't want to be coach Manuel Pellegrini picking his first team with all those individuals. I told Ronaldo he will end up playing centre half because they don't have one."
