Borussia Dortmund's coach Jurgen Klopp has expressed his puzzlement at new Paris Saint-Germain's buying policy.
Paris have spent some €250 million in transfer fees in the last two summers on big names such as Zlatan Ibrahimovic and Thiago Silva since Qatar Sport Investment took over from Colony Capital as owners.
"I find it much more exciting to help young players to develop," Klopp, who led Dortmund to league and cup success last year, told France Football. "It's crazy to spend so much and pay such huge salaries. It's not a fair policy. We've got a totally different approach compared to Paris Saint-Germain. When they try to put together big names, we try to find an efficient game.
"A team made of dozens or hundreds of millions doesn't interest me. I'm honest. If we met success in the last two seasons it's because we made an exceptional team work from a package of very good players."
On several occasions PSG have vowed, beside the big-name signings, to build up their academy and help young players to improve. Midfielder Adrien Rabiot, 17, who has two appearances to his name in the league, is the most common example.
The club also signed Italian youngster Marco Verratti from Pescara in the summer to underline that they are not only attracted by the stellar names in world football.
"Sign Thiago Silva, Ibrahimovic, Lavezzi - it's great for them. They are all exceptional players," Klopp said. "Paris can now play a big part in the European football."
