Liverpool were once again indebted to a contribution from the bench and a tactical tweak to beat Aston Villa on Saturday.
Alex Oxlade-Chamberlain and Divock Origi both made a positive difference as the Reds maintained their six-point lead at the top of the Premier League.
And Naby Keita was also on the pitch as, with Liverpool back to a 4-2-3-1 formation, Andy Robertson and then Sadio Mane struck to maintain the European champions’ long unbeaten top-flight run.
Those cameos mean Jurgen Klopp will now surely be tempted to rotate his resources for the Champions League group game at home to Genk on Tuesday.
Here we look ahead to the changes the Reds boss could make for the visit of the Belgians.
With Joel Matip out for the foreseeable, Dejan Lovren continued as centre-back partner to Virgil van Dijk at Villa Park.
Joe Gomez, though, is banging hard on the door, and it may be an opportunity for Klopp to give the England man another chance.
James Milner filled in at right-back in Belgium when Trent Alexander-Arnold didn’t travel due to illness.
And Klopp may decide to give one of his full-backs a breather ahead of Sunday’s Premier League visit of Manchester City.

One change that is almost certain is the recall of Fabinho to midfield, after the Brazilian was benched against Villa so to avoid a booking that would rule him out of the City game.
There could also be scope for a complete overhaul of the engine room, with it being a big ask for Adam Lallana to start three games inside a week.
Oxlade-Chamberlain and Keita are both vying for a start having featured in the same midfield in Genk a fortnight earlier.
Milner, too, is another option for Klopp to consider in midfield.
The Salah question
Mohamed Salah continues to be hampered by the ankle blow he suffered when fouled by Leicester City’s Hamza Choudhury almost a month ago.
He lasted an hour at Villa, and it would be no surprise for him to be benched on Tuesday.
Divock Origi’s recent contributions suggests he is worthy of a Champions League start.
