Team news: In a huge boost for the hosts, former Barca attacker Neymar has reportedly taken part in full training after missing a month due to a groin problem but it remains to be seen if Pochettino is willing to risk him from the off, no matter how much the Brazilian wants to turn out against his old employers. With Alessandro Florenzi also expected to overcome a muscular problem in time to line up at the Parc des Princes, PSG only have two confirmed absentees in Moise Kean (coronavirus) and Juan Bernat (ACL) for the second leg. Pochettino made a raft of changes for the Coupe de France meeting with Brest – as expected – so will welcome back the likes of Keylor Navas, Presnel Kimpembe, Marquinhos and Layvin Kurzawa to the rearguard on Wednesday. Idrissa Gueye and Leandro Paredes are set to man the engine room, while Angel Di Maria made his long-awaited return to action off the bench on Saturday and should be trusted from the first whistle here. Should Neymar not be risked from the off, Di Maria, Marco Verratti, Mbappe and Mauro Icardi will likely form the fearsome attacking quartet for the hosts. Barcelona are not so lucky on the injury front as Gerard Pique, Sergi Roberto and Ronald Araujo have all exacerbated previous injuries following their comebacks, although the latter is thought to have a good chance of returning on Wednesday. Attacking duo Ansu Fati and Philippe Coutinho are definitely out of this game, while Jordi Alba fell awkwardly on his arm against Osasuna but should be available for the second leg. Koeman has experimented with a 3-4-1-2 in recent matches and it has worked to great effect, so the Blaugrana boss may be tempted to stick with the same setup as Barca go searching for goals at the Parc des Princes. Aside from Junior Firpo potentially replacing Alba if he is not passed fit, Barca could name an unchanged side from the win over Osasuna, meaning that Ousmane Dembele may have to to make do with a spot on the bench once more.
