PARIS. Defending champions Paris Saint-Germain and fellow title hopefuls Marseille will continue to jostle for Ligue 1 supremacy with early-season pace-setters Monaco this weekend.Claudio Ranieri’s principality side retained their two-point lead at the top with a 3-0 win at home to Bastia in midweek, as PSG and Marseille kept pace with respective victories over Valenciennes and Saint-Etienne. Radamel Falcao scored twice at the Stade Louis II on Wednesday to take his season’s tally to a league-best seven goals, as Monaco extended their best start to a Ligue 1 campaign."As a striker of course I’m always happy when I score and that was again the case in the victory against Bastia,” said Falcao. Ranieri, though, said it was premature to cast Monaco, who only returned to the top flight this season after a two-year absence, as genuine title challengers despite their strong start.On Sunday Monaco travel to mid-table Reims who have lost just once in seven outings and conceded only one goal since mid-August.Second-placed PSG, who are in the middle of a run of five fixtures in 15 days, return to the capital on Saturday to host Toulouse.
