Ojo scored the second on the night as an experienced side progressed to the fourth round of the competition, and the teenager told the official Liverpool website that he was a little lost for words after finding the net on his Anfield debut.
He said: "It was amazing, honestly. I haven't got many words at the moment!
"I'm just happy that I could impact on the game and we could get the result to go through to the next round.
"It was a nice goal, a nice moment for me and obviously I'm really happy.
"Now, the main focus is move onto the next game, keep working hard, and if I get my opportunity again hopefully I can do well."
Given the changes that manager Jurgen Klopp made to the side for both games against Exeter, it has given the younger and more inexperienced members of the squad like Ojo a chance to impress and feel they can get more game time at the club.
Klopp has said that Ojo needs time to develop but seems fairly set on keeping his younger players at Anfield so he can develop a team rather than giving them individual experience on loan.
It will be interesting to see if Ojo features more as part of the matchday squad between now and the end of the season as Liverpool are short of natural wide players. Ojo seems very much at home in that role and has had an impact on both appearances in the FA Cup so far.
