Paris Saint-Germain suffered a shock defeat to Rennes at Roazhon Park on Sunday (Jan 15) evening. The defeat cuts PSG's lead at the top of Ligue 1 to three points thanks to Lens 1-0 win over Auxerre on Saturday. Despite having Lionel Messi and Neymar in the starting XI, PSG largely struggled to test a stern Rennes defence in the first half. In fact, it was Rennes who would create the better chances of the first 45. Arnaud Kalimuendo – up against his former club – was causing the PSG backline particular problems, forcing Gianluigi Donnarumma into a smart save on the half-hour mark from around the penalty spot. PSG tried to the turn the tide near the start of the second half when they introduced Kylian Mbappe and Achraf Hakimi. However, those changes didn't exactly work as in the 65th minute, Rennes took the lead.
