Attack
Forward - Sir Kenny Dalglish
Liverpool Football Club as we know it today would not have existed without the contributions of these three individuals - Bill Shankly, Bob Paisley, and Kenny Dalglish. Before Steven Gerrard, "King" Kenny was considered to be the best player to ever wear a red jersey; some people would say he still ranks over Gerrard on this list. No matter where you stand on this topic, it is indisputable that the former Scottish international is one of the greatest players to play in England's top division.
The Reds' dominance of England and Europe was all kickstarted when Paisley signed Dalglish in 1977. Over the next 13 years, the forward would establish himself as one of the greatest players ever, winning six league titles and three European Cups. Dalglish was a big-game player whose mere presence on the pitch elevated his team, and the former Celtic player was knighted in 2018 for his services to football. No Liverpool list is complete without the King, and he walks into this team with ease.
Forward - Wayne Rooney
The modern-day face of Manchester United, no player has scored more goals for the Red Devils than Wayne Rooney (253). Not only is Rooney one of the best players of this generation, but his storied career at Old Trafford has also made him one of the greatest players in the history of English football.
At his peak, there was perhaps no player as explosive and as complete as the former England captain. A prolific goalscorer, perhaps Rooney's most valuable trait was his ability to adjust and sacrifice for his team. Throughout his career, the forward has been deployed as an attacking midfielder, a winger, a false 9, a centre-forward, etc. Whatever role the manager needed Rooney to perform, he did it - and he did it with ease.
In the 21st century, no player has been more synonymous with the Red Devils as Rooney, and he is one of the main reasons why the club has such a huge fanbase across the world. As such, it is impossible to exclude "Wazza" from this list.
Forward - Ian Rush
One of the most prolific goalscorers ever, no player has scored more goals for Liverpool than Ian Rush. A complete striker who could finish with both feet and had an arsenal of attacking moves in his bag, the former Welsh international scored 346 goals for the Reds in all competitions in just over 650 appearances.
Having two different playing spells at Anfield, the Dalglish-Rush partnership was the best strike force in football for around a decade, and the striker is considered to be one of the top 3 players in the history of the club. He was voted into the PFA Team of the Century in 2007 and has won first Five Division titles and 2 European Cups with Liverpool. Due to his goalscoring prowess which is unmatched by any other player on this list, Rush completes our all-time combined XI of Liverpool and Manchester United players.
