MADRID (REUTERS) - As European heavyweights Juventus and Real Madrid prepare for tomorrow's Champions League clash at the Bernabeu, Juventus captain Gianluigi Buffon has questioned the Spanish side's "galactico" transfer policy.

The 35-year-old Italy goalkeeper, who played under Real coach and compatriot Carlo Ancelotti in a Juve team featuring his current assistant Zinedine Zidane, backed Ancelotti to cope with the huge pressure at the nine-times continental champions.

However, he suggested luring the world's top players like Gareth Bale and Cristiano Ronaldo was not enough to guarantee success in the modern game.

"The philosophy of 10 years ago remains the same, buy great champions, entertain the fans and maintain the historic prestige of Real Madrid," Buffon told Spanish sports daily Marca.

"But the reality is that in football, above all now, that's not enough to win," he added.

"It's better to have a project, balance and patience. Money is a good starting point but it's not enough in itself."

Ancelotti, who replaced Jose Mourinho at the end of last season, face a challenging week with tomorrow's game followed by Saturday's La Liga "Clasico" at Barcelona.

He has yet to get the best from his expensively assembled squad and their domestic campaign has begun in stuttering fashion.

They are flying in Europe, however, following thrashings of Group B rivals Galatasaray and FC Copenhagen in their opening two matches.

Victory against Juve will put them seven points clear of the Turin-based side with three games remaining.
