The Liverpool manager is poised to harness the work-rate and physical strength of 20-year-old Divock Origi rather than Sturridge in the eagerly-anticipated Europa League quarter-final against his former club.

Klopp will finalise his plans at a secret training session today having warned his players they will have to be at their very best if they are to remain in the competition.

"If we are not good tomorrow, it will be easy for Borussia Dortmund," said Klopp, who returns to the Westfalenstadion for the first time since leaving last May to embark on a short-lived sabbatical.
