But there is an obvious thing that PSG are now in optimal shape, and Liverpool, on the contrary, have not such good matches, where they began to concede more and lose points. I agree that the EPL is a more competitive championship and Liverpool is a very strong team, but if we evaluate the current state of the teams, I do not think that PSG is much weaker than Liverpool.
I think if we evaluate the current performance of both teams there is no difference, both teams from 5 matches in their local competition won almost all matches, a slight difference maybe from the number of draws where PSG got one compared to Liverpool who got 2 draws, but still I think the condition of both is in the best performance. The first leg was held at PSG home ground, it is an advantage for them to steal points. The most comfortable bet is a draw or BTTS.
