Coutinho was replaced on 70 minutes, having pulled up when put through on goal – with a 1 vs. 1 opportunity on offer for his hat-trick.
Replaced by Emre Can, the fear was that the Brazilian may have suffered a hamstring injury.
But Klopp confirmed in his post-match press conference that the Reds’ two-goal hero was only suffering from cramp, which can often occur on the first game of the season.
Klopp admitted he was wrong to celebrate with the players at 4-1 with half an hour to go, saying:
“I made a big mistake because I was involved in celebrations. It was the wrong sign for all of us – because we felt ‘that’s it’.”
Coutinho, Liverpool’s player of the year in the last two seasons, scored two stunning goals, and should now be fit to face Burnley next Saturday.
