Liverpool's trip to Old Trafford on Sunday highlights the growing gap between the Premier League leaders and rivals Manchester United.

Alex Ferguson famously declared he would knock the Reds "off their perch", a goal he achieved in some style by leading United to a lengthy period of domestic dominance, but there is no doubt who is on top now.

Liverpool are yet to drop a point this season with their winning run in the Premier League standing at 17 games, building an eight-point cushion over defending champions Manchester City.

United, meanwhile, sit two points above the relegation zone in 12th after losing 1-0 away to Newcastle United last time out, a result that increased the pressure on Ole Gunnar Solskjaer.

Sunday's Manchester meeting offers Liverpool a chance to secure more bragging rights and their players dominate the Omnisport combined XI ahead of the game.


Goalkeeper: ALISSON

Injury has kept Alisson on the sidelines for most of the season so far, but he could return from a calf problem at Old Trafford. David de Gea has looked vulnerable at times this season and he probably should have saved Patrick van Aanholt's late winner for Crystal Palace in August. Alisson was named The Best FIFA Men's Goalkeeper in September and it is hard to argue with that assessment given the transformative impact his arrival from Roma has had on the Reds.


Right-back: TRENT ALEXANDER-ARNOLD

Aaron Wan-Bissaka has made a promising start to life at United but, while he is extremely strong in the tackle, Trent Alexander-Arnold offers much more in attack. The Liverpool right-back created the decisive goal in last season's Champions League comeback for the ages against Barcelona, his quick corner enabling Divock Origi to strike the final blow. Few players, let alone those just 21 years old, would have seen the opportunity or had the quality to pull it off.


Centre-back: JOEL MATIP

There is perhaps a case to be made for Harry Maguire, one of the few bright spots in United's campaign, but Joel Matip has taken his game to a new level this season. He is a key part of the tightest defence in the league this season, with Liverpool having only conceded six goals. And when Matip sat out the Champions League group game against Salzburg, Alisson's deputy Adrian was beaten three times.


Centre-back: VIRGIL VAN DIJK

There can be no arguments here, with Virgil van Dijk one of the first names on a combined XI team sheet. The Netherlands international cost a world-record fee for a defender when he eventually made the move from Southampton, but that £75million now looks like money well spent. Van Dijk has led Liverpool's defence to the Champions League title and a long-awaited Premier League crown could well follow this season.


Left-back: ANDY ROBERTSON

Similarly, Andy Robertson is a no-brainer at left-back despite Luke Shaw's improvement over the past year or so. The Scotland captain is arguably the finest player in Europe for his position now and was a superb bargain buy at just £8m from Hull City in 2017. His clash with Lionel Messi in the early stages of the Champions League semi-final at Anfield set the tone for the Reds' comeback.


Central midfield: FABINHO

It took time for Fabinho to settle after joining from Monaco, but the former right-back is now a key cog in Liverpool's relentless winning machine. It is impossible to leave him out of the combined XI given United's offerings as midfield protectors include mediocre options such as Fred and Scott McTominay.


Central midfield: PAUL POGBA

There is a spot for Paul Pogba, though, despite the World Cup winner remaining something of an enigma. Pogba was United's top scorer in the Premier League last season, also providing a team-high nine assists. He may not always hit top form, but at his best the ex-Juventus star remains an elite performer. Pogba could add an extra gear and more quality to Liverpool's occasionally one-paced midfield.


Central midfield: JORDAN HENDERSON

Liverpool captain Jordan Henderson completes the midfield, providing experience and leadership. The England international is still underrated by some, but Henderson showed his importance to the Reds at the end of last season when he was utilised in a more advanced role by Jurgen Klopp. He displayed a fresh dimension to his game with creativity and incision in the final third.


Right wing: MOHAMED SALAH

Yet to hit top form this season, Mohamed Salah is another mandatory pick for Liverpool after his stunning goalscoring exploits since joining from Roma. The Egypt star has hit 77 goals in 116 appearances for the Reds, making Chelsea's decision to allow him to leave Stamford Bridge in 2016 look rather foolish. Salah's selfish streak may sometimes appear to annoy team-mates, but his individual brilliance can carry Liverpool through tight games.


Striker: ROBERTO FIRMINO

Leading the line is Roberto Firmino, with the Brazil forward's incredible energy, work rate and ability to operate between the lines giving Liverpool a platform to thrive. With Marcus Rashford having only scored once since the opening weekend it is impossible to argue for the United striker here, with the England international's confidence having looked very low of late.


Left wing: SADIO MANE

With eight goals in all competitions this term, Sadio Mane is Liverpool's top scorer in 2019-20 and he is another Red it is impossible to leave out of a combined XI. Senegal star Mane is one of the many ex-Southampton players to have flourished at Anfield and though Anthony Martial has sporadically impressed for United, he is not quite in the same league.


Substitutes

On the bench there is more room for United talent as De Gea and Maguire would be included. James Milner's versatility makes him a must, while the midfield drive offered by Alex Oxlade-Chamberlain and Georginio Wijnaldum would see them be useful subs. If fit, Martial would join Champions League final hero Origi as forward options.
