The Brazil international was on the score-sheet as Liverpool came from behind to beat Stoke on Saturday to keep their top four ambitions alive.
Coutinho was almost dropped from the team due to illness, but made a shocking return to play at the bet365 Stadium amid pain.
“I joined up in the morning [of the game]. They asked me to stay at home because I was not feeling well but I wanted to be here,” said Coutinho.
“I wanted to be involved with the team. The manager decided because I was not 100 per cent.”
“I want to keep going to keep scoring and helping my team and keep learning from my manager. This was a big win. There are a lot of points to fight for and every game for us is important.”
Jurgen Klopp’s men were aided by the return of Roberto Firmino and Coutinho’s form as they managed to make a dramatic comeback.
