He needs to do it soon if he wants to secure a place in the Play-off zone, but the problem is that in the next game Man City will face PSG who are also in desperate need of a win. This match is very crucial for Man City, they must succeed in securing victory in the remaining two games to survive in the UCL.
Guardiola will compete tactically with Luis Enrique to compete for three points, almost the same philosophy applied by both coaches makes this match very tense, Man City is a little under pressure because they will play at PSG headquarters.
I have an assumption that in the match Man City will most likely win and the worst results will end in a draw.
Maybe this is a little unreasonable but for me Man City deserves to defeat PSG on the grounds that Man City is still strong enough to defeat PSG who is not too experienced.
So most likely there are only 2 possibilities and PSG cannot do much unless it will only hold a draw.
