Jurgen Klopp admits he might be unable to use his new-look formation when Liverpool are hosted by Rangers on Wednesday night in the Champions League due to injuries.
After switching to something of a 4-4-2 in the 2-0 win over Rangers on Tuesday evening, Klopp named an unchanged side at Arsenal on Sunday as his team were beaten 3-2 by the Premier League leaders.
First-half problems for Luis Diaz and Trent Alexander-Arnold however, means the Reds may be forced into a tactical rethink when they make their first-ever competitive visit to Ibrox on Wednesday evening.
