Sharjah24 - AFP: A Paris Saint-Germain side missing the injured Lionel Messi and Kylian Mbappe and hit by a stomach bug warmed up for their Champions League showdown against Bayern Munich by falling to a 3-1 defeat at Monaco in Ligue 1 on Saturday.

All the goals came in the first half at the Stade Louis II, with Aleksandr Golovin putting Monaco ahead inside four minutes and Wissam Ben Yedder doubling the home side's lead.

The 16-year-old Warren Zaire-Emery pulled one back for PSG but Ben Yedder scored his second of the game, and 19th goal this season, to make it 3-1 in first-half stoppage time.

PSG remain top of the table, although their lead has been reduced to five points over Marseille, who won 2-0 at Clermont.

Monaco are now up to third, seven points behind the leaders, but seeing the gap to their rivals reduced is the least of PSG's worries right now, after they went down to their second defeat in four days.

Also beaten by Marseille in the last 16 of the French Cup in midweek, Christophe Galtier's team have now lost three times in seven league outings in 2023.

PSG will be without Mbappe, their top scorer, due to a thigh injury for the Champions League last-16 first leg with Bayern at the Parc des Princes on Tuesday.

Galtier must also hope that Messi recovers in time from the hamstring complaint that prevented him from travelling to the principality.
