I put Liverpool as Jupiter because the world expect them to take over the match. Calming Man City were quite on form last game against Southampton, so I assign them to Venus.
Jupiter will no help in the sky, meanwhile Venus will have very great positive reception from the Mars. Man City would win.
On tactical stand point, if Liverpool risking play with double six as last game against Arsenal, they would struggle to control the midfield area. This is because Man City always put 3-4 people in the midfield.
