ESPN FC Extra: France's elite meet in Paris
Paris Saint-Germain manager Laurent Blanc has said the French champions attempted to sign Mesut Ozil from Real Madrid before he joined Arsenal.
Johnson: Defensive dilemma
The Gunners paid a club-record €50 million to sign Ozil, 24, on transfer deadline day earlier this month.
PSG had also been linked with Chelsea's Juan Mata -- and Blanc said he would have welcomed either player to the French capital.
"Both of them would have done us good," he told former France international Luis Fernandez on RMC Radio. "The only attempt made, as far as I know, was for Ozil."
But PSG, having already spent over €100 million on Napoli striker Edinson Cavani, Roma defender Marquinhos and Lille full-back Lucas Digne, did not take their interest in the Germany midfielder any further.
Blanc also reflected on the departure of defender Mamadou Sakho, who joined Liverpool for €19 million last month.
"In the off-season we signed Marquinhos, who plays in the same position," he said. "There were five central defenders for two places, so there was one too many. I said it to him.
"Initially, Mamadou accepted the competition. But we're in a World Cup year, and I know what that can produce in a player.
"He wanted to leave PSG to have more game time. He made a choice. He chose a very big club in Liverpool. I wish him the best."
Their title defence will face an early test when they host fellow big-spenders Monaco on Sunday.
A switch to a 4-3-3 formation has resulted in an upturn in form, but Blanc said he was not yet tied to a certain system.
"It could be suitable because we've used it for three matches and the results are there," he said.
"But I think we don't have to focus on one system of play. We have very versatile players. What interests me is that the team is as effective as possible.
"If we have to play in the same system as last year, so that the players will be effective and feel comfortable in that system, then I'll adopt it."
