AC Milan technical director Leonardo has warned new Chelsea boss Luiz Felipe Scolari off of making any move for Brazilian superstar Kaka.

Scolari is expected to receive a huge transfer budget as he takes on the role at the Blues helm and Kaka is said to be a top target for the manager.

"It's normal for a Brazilian coach to try to bring in Brazilian players," Leonardo said.

"But signing Kaka is impossible, because he is here at AC Milan and will be here until the end of his career."

However, Leonardo has backed Scolari to be a big success, having played under the man when he was coach of Brazil.

"Chelsea need an important victory - they are looking to the Champions League," said Leonardo.

"Scolari won the World Cup with Brazil in 2002 and then took Portugal to the finals of the European Championships two years later. So I think he is a good appointment.

"Chelsea were the nearly team of European football last season. They came so close to the Champions League and Premier League.

"I think Scolari can bring something more to them, so they arrive at the right result next time."
