Messi is back! Five things to watch during Ligue 1 Matchday 18

Wednesday's Ligue 1 matches are all on BT Sport. Paris Saint-Germain are boosted by the return of Lionel Messi. They lost 3-1 at second-placed Lens on New Year's Day. Angers have suffered nine defeats on the spin and are bottom of the table. Messi and Neymar should be back for PSG's game against Anger. They will play either side of Kylian Mbappe. Azzedine Ounahi and Sofiane Boufal have returned from their own post-World Cup break. The match will be played at the Parc des Princes.

Lorient are back up to sixth place in Ligue 1 after beating Angers. Eric Roy has been appointed as manager of Brest after a three-month search. Bosth rose from bottom to 17th place under Bruno Grougi, but are still two points behind Ajaccio and safety. Auxerre are 18th and need a win to stay in the top flight. Paulo Fonseca's Lille are at home to Best.  Auxerres are also looking for a victory. They are currently 18st and on goal difference.

Messi is back. Nantes, Lyon, Brest, Lille, PSG, Nice, Montpellier, Troyes and Marseille are playing on Wednesday.
