PSG has continued its spending spree with the signings of Brazilian defenders Alex and Maxwell, but will be without its most expensive addition, Javier Pastore, on Saturday at Brest.

Pastore, acquired for approximately $55 million in the summer from Palermo, is out three to four weeks with a muscle tear suffered last Friday in the Coupe de France.

Maxwell was signed earlier this month from Barcelona, and Alex followed him to Paris on Friday from Chelsea. The latest additions push the club's signings to around $125 million under their new Qatari owners.

With a three-point cushion over Montpellier atop Ligue 1, PSG has used its new players to emerge as the dominant team in France. But a tricky trip to Brest - which has not lost at home - awaits this weekend.

"Everywhere we go this year, people are waiting for us," said PSG midfielder Clement Chantome. "They are unbeaten at home so we know what to expect."

PSG was eliminated from the Coupe de la Ligue and the Europa League, leaving a Ligue 1 title and Coupe de France crown as the remaining targets.

With Carlo Ancelotti perfect since taking over with a pair of Coupe de France wins and one Ligue 1 win, the pressure will be on PSG not only to remain atop the standings and advance in the Coupe, but to excel week-to-week.

"What's really new about PSG is that now we're an ambitious club that wants to go all out to win titles," said Chantome. "What has arrived at the club is a very promising potential. I'm ambitious, I know what's expected of me and all I want is to get out there and win titles with this club."

PSG has not lost in its last eight in all competitions, so Brest will have one huge mountain to climb this weekend to remain unbeaten at home.

Montpellier visits Nice on Saturday, when defending champions and third-place Lille hosts St. Etienne. Auxerre hosts Nancy, Lorient hosts Sochaux, Lyon hosts Dijon, and Toulouse hosts Caen in Saturday's other matches.

On Sunday, Evian hosts Bordeaux, Valenciennes hosts Ajaccio, and Rennes hosts Marseille in a battle of top-six clubs.
