PARIS (AP) — Paris Saint-Germain dominated Ligue 1 last season, losing only two games as it benefited from a lack of domestic rivalry to also embark on a victorious Champions League campaign. But things might prove more difficult for coach Luis Enrique and his PSG team this season, because Marseille and Monaco are determined to mount credible title challenges after strong summer signings. PSG also has a long-awaited local derby against newly-promoted Paris FC to contend with.
