It is no surprise to see the Liverpool's number one in as the goalkeeper for this combined eleven.
His performances for club and country have been phenomenal over the last few years. He has well and truly cemented himself as one of the best between the sticks in world football.
Trent Alexander-Arnold has been one of, if not, the best right back over the last few years. In the past there have been doubts about his defensive capabilities but over the past six months, he has put those worries to bed.
No player in the world is replacing him in a combined eleven - this shows how consistent he has been and also what he has achieved already in such a short career.
Alexander-Arnold is an excellent passer of the ball and has enjoyed twenty-two assists since September 2019.
The Portuguese centre half is a colossal presence at the back. His physicality and aerial ability, previously seen at Real Madrid, gets him into this combined eleven even at 38-years-old.
The three-time Champions League winner is one of the all-time greats, despite his reputation for a challenge!
Virgil Van Dijk
The effect that Van Dijk has on his club and country is enormous. This was appreciated during his spell on the sidelines, since October last year.
Ever since his return, he has been superb and showed that he is like no other in his position.
The 30-year-old brings a more direct approach to the Reds' game allowing them to build attacks quicker due to his frequent long balls out from the back.
Similar to Alexander-Arnold, Andy Robertson has reached ridiculous numbers over the past few seasons. His assist input has been immense and defensively he has been very good.
He has had a tricky start to the season and has struggled to show the form he is capable of, due to injuries but also the form of Kostas Tsimikas.
It is uncertain who will be given the nod for Tuesday's clash, however, Robertson's form and numbers in the past cannot be disputed.
Fabinho has cemented his place in that defensive midfield role under Klopp. He is one of the first names on the team sheet, and he has been key to Liverpool's success in the Premier League and the Champions League.
The Brazilian is instrumental to Liverpool's style of play and without his protection, there is a feeling of vulnerability within the team. He HAS to be in this combined eleven.
Another player, who is instrumental to Liverpool's style of play is Henderson. The captain drives the team on and without him the team is considerably weaker.
He is the current longest serving player for the club and his appreciation hasn't always been there during his time at Anfield. His match winner last time out against AC Milan was a beautiful strike and he rightly gets into this combined eleven.
Despite being born in Brazil, Otávio won his his first cap for the Portuguese national team last month. He is a very creative player who can play anywhere across the forward positions.
He is given the license to hover and drift deeper but also be allowed to get in the more advanced positions. Otávio is what Phillipe Coutinho was to Liverpool and is a wonderfully gifted player.
He can both score and assist and is good with both of his feet. He makes up what is very few Porto players in this combined eleven.
What can be said about Salah? He is Liverpool's main man and regularly creates chances and sets players up in the team. He has a knack of scoring goals, which all great goal-scorers have.
However, a bit of a contract dilemma is building with the 29-year-old yet to put pen to paper to a new deal, with his current contract expiring in 2023. When it comes to the best attackers in the world, Salah is most certainly there.
Mané along with Salah has produced unbelievable figures when it comes to scoring and setting up goals. In Liverpool's 5-0 thumping at Porto back in 2018, Mané ended up picking up the match ball in what was a sensational display all round.
Although his form of late hasn't been too admirable, he is still a brilliant player and deserves to be in this combined eleven without doubt.
The ex-Porto man is set to face his former team for the first time since he left on Tuesday. Ever since his move to Liverpool last year, he has forced himself into the starting eleven due to his clinical finishing and ability to take on players.
The 24-year-old still has stuff to work on, especially defensively and is by no means the finished product. However, he is one hell of a player and will almost certainly cause the Porto defenders trouble if selected to play on Tuesday.
