WATCH: No one can quite believe what just happened in the Liverpool v Plymouth match

It's been a long time since we've seen this man score.

Anfield stalwart, Lucas Leiva, hasn't played as much football as he would have liked over the last couple of months. He has only started three Premier League games for the Reds this season and it would seem like his time on Merseyside is coming to a close as he has been heavily linked with a move away from Anfield this January transfer window. The 30-year-old is currently the longest serving player at Anfield and it would be with a heavy heart if he was to leave the club. However, Klopp has handed the Brazilian a rare start in the 3rd round FA Cup replay with Plymouth Argyle at Home Park. The Brazilian repaid his manager's faith in him with the game's opening goal. Lucas scored with a near-post header on 18 minutes to give his side the lead. The interesting thing about this, however, is that this was the first goal Lucas has scored in seven years. https://twitter.com/SportsJOEdotie/status/821816197247303681 Philippe Coutinho put in an excellent in-swinging corner kick which Lucas latched on to power home at the near-post. https://twitter.com/LFC_Vines/status/821811647014703105 As you would imagine, Liverpool fans rejoiced in Lucas rediscovering his goal scoring touch. https://twitter.com/empireofthekop/status/821812686279311361 https://twitter.com/LFCFansCorner/status/821810872783958017 https://twitter.com/noahandrew1st/status/821816309335859206
