After positive results in the first game for both these teams, Liverpool and Porto will both be looking to take another step to qualification from the A group. This trip has been a successful 1 for Liverpool in recent history so it'd be no surprise if Liverpool came away with another win.
However, we should not underestimate Porto. With a hard earned draw away to Atletico Madrid, Porto will set to up to frustrate once again and it's up to Liverpool to break them down.
Liverpool will want to bounce back after the 3-3 draw at Brentford at the weekend. This could be dangerous for Porto. Liverpool will attack from the outset, trying to end the game as early as they can. Porto will have to soak up the pressure and stay in the game.
The longer Porto keep Liverpool to 0-0 or even 1-0, the longer Porto will be more confident in getting something out of the game. With Liverpool's attacking prowess I expect Liverpool to score early in this game.
Liverpool's left hand side will be key to this game as Porto's right side can be got at. I can see plenty of space for Robertson to run into, especially if Mane runs with the ball as he will attract players to him.
With the time and space to work with, Robbo's delivery into the box will be important. Jota and Salah will be the players that will be getting on the end of these crosses and I expect them both to add to their amazing goal records.
I believe the midfield three will be high up the pitch and whoever the two are playing alongside Fabinho will have plenty of chances to get into the box themselves. Whether it be Keita or Jones starting, I think both will get plenty of opportunities to copy their recent long range goals.
Porto's game plan will be basically to keep Liverpool out and counter. Even if they lose a goal, they will be happy to go into the break one goal down.
Two banks of four will be set up with early balls out to Martinez and Taremi to start their attacks. The pace of Porto's attacking players will help their chances of nicking a goal which will have Klopp thinking about keeping Fabinho back a bit.
This game for Porto will come down to taking their chances when they get them. Former Liverpool player Grujic will be a key player in this game as he will be the one to start the counter attacks. If he can get the ball into the attackers quickly then Porto will become a threat to Liverpool.
For me, this game only goes one way. As much as Porto will set up to be stubborn and hard to break down, I believe Liverpool will score quite early on in the game. The press of Liverpool will be too much for the Portuguese side.
Liverpool, when confident can score for fun. Unfortunately for Porto, this could be one of those nights.
My prediction is an easy win for Liverpool with Jota and Salah amongst the goals. Liverpool's left side will be the biggest threat and I think Robbo will get an assist or two.
