Liverpool goalkeeper Adrian praised Fabinho for his performance in their Champions League win at Ajax.
With Joel Matip and Virgil van Dijk injured, Fabinho excelled as makeshift centre-back alongside Joe Gomez to ensure Liverpool kept only a third clean sheet in their last 14 games.
And Adrian believes the impact of the Brazilian at the back will only improve with time.
"Fab played a few times there last season and the more games playing together, everyone is going to get more confident, for sure," he said, speaking to liverpoolfc.com.
"We've known each other for a long time and it's not just the centre-backs and the goalkeeper, it's the whole team defending and it was a very good job from everyone.
"Obviously we know we are going to miss Virgil and it's a big loss for us, but it's how to react. We have many good players who can play in this position – Fabinho did great with Joe."
