The Brazilian will miss both legs of the tie against United due to a metatarsal injury in his right foot, the same problem that forced him to miss the second leg of PSG's defeat to Madrid past year. After he left the pitch, it was more hard for us to control the game. "If we don't dream and we don't have that vision of where we are going, then we will just falter", said Solskjaer.
"We have lots of Plan Bs".
Cavani's fellow forward Neymar has already been ruled out of the United games with a broken metatarsal. We have to play a big match. "But we will be ready on Tuesday".

PSG may now have to field a front three of Julian Draxler, Angel Di Maria, and Kylian Mbappé, which is. not bad. Verratti played nearly an hour before being substituted by Leandro Paredes.

Mario Balotelli and Lucas Ocampos scored as Marseille won 2-1 at Dijon on Friday.
