The chances are that at least one of the high-profile trio will extend their deal — Salah, 32, and Van Dijk, 33, are more likely, while Alexander-Arnold, 26, seems set to move to Real Madrid — but the club should certainly think about possible replacements for all three in case the worst happens.
Here’s a list of new players who could be the best fit for each position next summer.
On the surface, finding a world-class central defender might not appear the trickiest task given the quality of candidates. Yet Van Dijk is arguably the best centre-back in the world, and no data or traditional scouting methods are going to miraculously toss up a ball-playing defender who is such a natural leader, fast, unbeatable in the air and whose game-reading skills are so impressive that he hardly needs to make a tackle.
Tah was outstanding for Leverkusen last season, and has been equally dominant this campaign. There are several factors that make his profile a pretty close match to that of Van Dijk: he’s physically imposing, a leader who plays with an air of calm, is an extraordinary distributer of the ball (4.6 progressive passes per 90 minutes) and his elevated reading of the game ensures that he only goes to the ground as a last resort (0.5 tackles per 90 minutes.) In addition, he hardly ever misses a game through injury, and his contract expires in the summer, meaning he will be available as a free agent.
Barcelona and Bayern Munich are reported to be interested in making a summer move, and there still are a few doubts for Liverpool. Tah hardly covered himself in glory during Leverkusen’s 4-0 defeat at Anfield in November, mostly features in a back three, and is coming towards the end of his career. But he’s the best fit to replace Van Dijk.
OTHER OPTIONS
Marc Guéhi, 25, Crystal Palace: The England international has been linked with a £70m return to his former club Chelsea, but could also see Liverpool come in for him. This season he lined up as the left centre-back in a duo (prior to Crystal Palace boss Oliver Glasner switching to a back three), despite being right footed, and has even deputised as a defensive midfielder.
Further to his credit, he is club captain when Joel Ward is out and is often lauded for his leadership. He has pace in abundance and defends the box well, but his aerial game leaves something to be desired (62% success rate is on the low side) and his progressive passing may be exposed in a possession-heavy side.
Castello Lukeba, 22, RB Leipzig: Lukeba has been on the radar since he broke through at Lyon at the age of 19, though he has had an underwhelming debut season at Leipzig. Exceptionally quick and agile, Lukeba is also a fine passer of the ball who is typically tasked with bringing it out of defence.
Being left-footed, he’d naturally slot well into the spot vacated by Van Dijk and much like the Liverpool captain, he prefers to use his strength, speed and agility to dispossess opponents instead of diving into tackles. He is also years away from his prime.
Ousmane Diomande, 21, Sporting CP: One of the strongest defenders around, Diomande is brilliant in the air and plays with admirable supplies of confidence for one so young. He’s so good on the ball, but is likely to be viewed as too adventurous and still needs to improve his decision-making.
He could have been an intriguing signing to play alongside Van Dijk rather than replace him.
Micky van de Ven, 23, Tottenham: One of the quickest centre-backs around, Van de Ven anticipates the game well, defends on the front foot and is left-footed. Few can match the Dutchman for his attacking contributions — progressive passing and advancing with the ball — but he is under contract for another 4 ½ years and there’s no way Spurs would entertain offers from a rival.
Alessandro Bastoni, 25, Inter Milan: Another dominant left-footed central defender. Bastoni is solid at the back — though being supported by two additional centre-backs makes life easier — and he’s one of the most productive in Europe from an attacking perspective (distribution, carries). However, his transfer would cost around €100m.
