The Reds were left with only one senior recognised centre-back in Virgil van Dijk for the game against Brighton as Dejan Lovren and Joe Gomez were out injured, while Joel Matip was not match fit and only made the bench.
Salah was awarded another penalty against Brighton on Saturday after being clearly fouled by Pascal Gross and the Egyptian was subsequently booed by the crowd at the Amex Stadium after converting the spot-kick. Salah scored his team's winning goal at the game as he successfully converted the penalty.
Fabinho dealt with Brighton's long balls and was untroubled while bringing the ball from the back as Chris Hughton's side rarely pressed the Liverpool defence.
Notable admirers included team-mate Andy Robertson, "For somebody playing out of position, he covered so well, he cleared away and had so many good blocks".
Joe Gomez is still out with a foot injury although Cameroon worldwide Joel Matip has returned to training after recovering from a broken collarbone.
"He did well in these situations and with the ball it's absolutely clear".
"Trent on the ground - he's a hard boy so that's not a good sign and the doc came, something with the ankle", said the 51-year-old German. He made the sprints but I didn't like the way he did the sprints because when he slowed down, it looked a bit like limping. "Of course he would have preferred to play further forward in the last couple of games but we needed him to help keep a clean sheet and we managed it so all credit goes to him for that".
"The break that we are getting at the end of January is going to be 100 per cent helpful for the boys with injuries", the boss told the Liverpool Echo. 'We went for it in the latter part of the game and showed a real intent to get back on level terms. I'm sure Fabinho would have preferred to play as the No.6 but that's the attitude we have in the squad.
