Exeter City manager Gary Caldwell has said his players should be looking forward to "creating history" against Middlesbrough in the Carabao Cup.
It is just the second time Exeter have reached the EFL Cup fourth round.
They progressed by beating Premier League side Luton Town 1-0 in the third round in September.
"If we do win then we are creating history - and that's something that should be really exciting for the players," Caldwell told BBC Devon.
"They should be really looking forward to it and go and give it absolutely everything."
Exeter go into Tuesday's home tie in their worst run of form since Caldwell took over at St James Park a year ago.
