I think both teams will be able to score goals, 2-1 for PSG victory. Lautaro Martinez will definitely be the mainstay on the Inter Milan side, and Dembele will be the one who is expected to score goals for PSG. If Inter Milan defense is tight enough, it will provide a great opportunity for players like Achraf Hakimi to score goals from outside the penalty box. However, that is just a personal assumption that of course can be wrong, and I realize that everyone has their own views.
The goal scenario in my opinion would have been better if Inter Milan had fallen behind early so Inter's play would have been more offensive. If Inter open the scoring first, it's likely that the game will be slow because Inter are good at defending.
A big influence in Inter Milan's line-up is Lisandro Martinez. The Argentine striker has good attacking instincts despite his stocky build.
PSG have Dembele, Kvaratskhelia and Barcola who will trouble the Inter defense. The three of them must be well covered by Inter's defense as any one of them will be a nightmare for Inter.
