Liverpool had Alisson Becker, as much as Mo Salah, to thank as they progressed to the last-16 of the Champions League courtesy of a 1-0 win over Napoli.
Paris Saint-Germain topped the group, but Anfield was buzzing nonetheless after a result which once again has the Reds dreaming of a run to the final like last season.
The key difference, of course, is that back in May, they had Loris Karius between the sticks against Real Madrid.
We all know how that turned out.
Fast-forward a few months, and having encouraged the club to pay a then-record £67million for him, Alisson is quickly repaying their faith.
In the final moments against Carlo Ancelotti's side, the 26-year-old threw himself at Arkadiusz Milik's shot and used his legs to keep it out.
Yes, Milik might have done better - it was straight at the 'keeper - but Alisson deserves full credit for making himself big and having the reflexes to keep the ball out.

It's far from the first time the stopper has saved his new side this season - in fact, bar that one howler against Leicester, he's been pretty superb consistently.
When the best goalkeepers in the world are discussed - among the likes of David de Gea, Manuel Neuer, and Jan Oblak - his name is now in the frame.
It's a pertinent question - how does Alisson compare to the very best? Well, Opta have now done some of the ground work.
Alisson has recorded a very impressive stat
According to their xG model - which records the quality of chances which are created and conceded, rather than just the number - an average goalkeeper would have let in eight more goals than Alisson in the Premier League and Champions League combined.
It's a far more effective way of analysing his performances - it takes into account factors such as whether the striker is in space and how far from the goal he is.
When all that is considered, the former Roma man has let in just six league goals - three fewer than Manchester City's Ederson. In the Champions League, his tally stands at seven from six games.
That goes a long way towards explaining why Liverpool sit top of the table and can now look forward to another run in Europe.
It could all have been very different if they hadn't been willing to spend the big money in the summer.
