Christophe Galtier is seriously considering changing the system, he who since his arrival at PSG has opted for a system with three defenders. Given the players he currently has, especially in defense where Sergio Ramos is not the most reassuring as a right central defender, the Parisian coach is thinking of returning to his classic 4-4-2 system which would allow him a better defensive base.
Galtier would thus alternate between the two formations as he said in a press conference where he felt it necessary to be able to alternate between two systems. It remains to be seen what role Neymar or Messi will play in a system with only two forwards.
