Klopp claims "fired up" Darwin Nunez was unhappy

Darwin Nunez came off the bench to score twice in the final 10 minutes as 10-man Liverpool came from a goal down to stun Newcastle 2-1 at St. James' Park on Sunday.
The Uruguayan striker failed to live up to the expectations of his £85m signing in his first season with the Reds, and had not started any of the Reds' first three Premier League games so far this season.
The German coach was asked about the former Benfica player's lack of playing time at a press conference to which he replied: "He was obviously fired up from not playing, not starting, then put all the energy in these two shots.
The former Borussia Dortmund">Borussia Dortmund coach was also asked if Nunez's role could change after his stellar performance against the Magpies. "Really, I understand the question. It’s clear he’s not happy – how can a player be happy when he’s not starting. The thing is it’s early in the season, we need to find stability, we need to find a formation, we need to get results," he said.
"We’ll play every three days anyway and everybody will play, there’s no doubt about that," concluded Jurgen Klopp.
