A baptism of fire for new boy Alberto Moreno also served to bring fellow new boy Dejan Lovren down to earth with a bump after a smooth start at Liverpool.
The defenders, costing a combined £38 million, were put to the sword by a clinical Manchester City side who won 3-1 at home to the Reds.
A watching Jamie Carragher was unimpressed in the SkySports studio, and made clear he felt the pair struggled.
He said: "He (Lovren) didn’t play well. The whole back four never really functioned well and there were problems down that side with Moreno coming in for his first game. He has had a difficult night with Moreno on that side.
"It’s basic back-four work and it’s something that Liverpool are going to have to work on because if it happens a lot in this league, you’re going to get punished."
In hindsight, playing two defenders who had never featured alongside each other was asking for trouble away from home against the Premier League champions.
Buoyed by the arrival of Mario Balotelli, the club could have lost a little focus in the run up until kick-off against a City side determined to assert their dominance as champions.
Lovren and Moreno have every chance to get it right, and they will need to do so for the Reds to succeed. They should take heart from the poor start Patrice Evra and Nemanja Vidic had at rivals Manchester United in 2007.
A year later the pair were Champions League winners. It's a leap of faith to assume Liverpool can do the same, but they are certainly closer than United to achieving so right now.
