League Two side Exeter missed out on a famous FA Cup win as a young Liverpool side came from behind to force a third-round replay.
Reds boss Jurgen Klopp had made 11 changes and his side fell behind early on when Tom Nichols poked in.
Jerome Sinclair equalised with a low finish but the hosts retook the lead when a Lee Holmes corner went straight into the goal.
With time running out, Brad Smith rescued Liverpool with a neat finish.
The replay at Anfield means Exeter could earn about £700,000 from the match, according to Sporting Intelligence.
"I'm a football manager and I want to win games. When you're 2-1 up and defending a lead with 10 minutes to go then you're disappointed" said Exeter boss Paul Tisdale.
"But we got a draw against a very good side and have a replay at Anfield. We have no investor so every penny counts. At the end of the day we've put on a really good show."
The date of the replay is yet to be confirmed, but both teams will be in the hat for the fourth-round draw, which takes place on Monday.
