Gomez has also endured serious knee and ankle injuries since joining the Reds in 2015. But Klopp remains confident Gomez still has a big part to play after extending his spell on Merseyside.
"One of the many wonderful things about Joe is he has experience and youth, that's not a bad combination," Klopp said. "He has not long turned 25 but he was at the club before I was. The best thing of all is that his best years are still to come, and I could not be happier that this will happen with us."
Gomez, who was signed from Charlton, has helped Liverpool win the Champions League, Premier League, FA Cup, League Cup and FIFA Club World Cup.
