Alexander Isak was notably absent from Liverpool's starting lineup for their highly anticipated clash with Manchester United at Old Trafford this afternoon, leaving fans and pundits alike questioning the Reds' attacking firepower.

The Swedish striker joined Mohamed Salah on the sidelines after both players missed out from last weekend's victory over Crystal Palace. Salah had been substituted with a muscle injury, which he later confirmed was minor, but Isak's absence came as more of a surprise to many supporters.

Reports in the 24 hours leading up to kick-off suggested Liverpool's record £125 million signing would be unavailable, and the team sheet confirmed those suspicions. According to Paul Gorst of the Liverpool Echo, Isak is dealing with a "minor groin issue" that the club is treating with extreme caution. "I'm told it's not seen as a serious one," Gorst wrote, "but the club are in no mood to take any risks with a player who only returned from four months out with a broken leg, sustained before Christmas."

This cautious approach makes sense for a player of Isak's caliber, especially given Liverpool's significant investment in him. However, it leaves manager Arne Slot with a serious dilemma in attack. With Salah and Hugo Ekitike already ruled out, the Reds are dangerously thin up front against one of their biggest rivals.

"It's a shame in one sense, but the plan has to be absolutely about getting Isak right because Liverpool have bet the house on the £125m man," Gorst added. "You do worry where the goals will come from today, however, with no Mohamed Salah, Hugo Ekitike or Isak. Cody Gakpo simply has to step up and put in the sort of performance he did so often last season… let's not sugarcoat it, there is very little firepower in this team today."

The injury crisis has forced Slot to name an extremely youthful substitutes' bench, with six players under the age of 21 included. At 22 years and six months, Milos Kerkez is actually the third-oldest player in reserve for the Reds this afternoon—a startling statistic that highlights just how stretched the squad is.

For Liverpool supporters, this match represents a true test of depth and resilience. With key stars missing and a bench full of promising but inexperienced youngsters, all eyes will be on Gakpo and the remaining starters to deliver against a Manchester United side eager to capitalize on the Reds' misfortune.
