The 26-year-old has been unable to get anywhere near matching the hype or his eye-watering £125million price tag since completing his acrimonious deadline-day switch from Newcastle.

Isak has only managed 16 appearances for Liverpool having had to play catch up in terms of fitness and deal with some minor injuries before suffering a significant issue in December.

The Sweden international was hurt in a tackle by Micky van de Ven when scoring the opening goal in a 2-1 win against Tottenham, leading to surgery on an ankle injury which included a fibula fracture.

Isak’s absence has been keenly felt and his place in the 21-man squad for Wednesday’s Champions League quarter-final first leg at PSG could be a major boost for Arne Slot’s stumbling side.

Pressure is mounting on the Dutchman and his team after concerning recent performances were compounded by Saturday’s humiliating 4-0 loss at Manchester City in the FA Cup quarter-finals.

Isak returned to team training last Thursday and worked with his team-mates on Tuesday morning before jetting off to France.
