Oxford United midfielder Eddie Hutchinson (pictured) believes all the pressure will be on Southend in tonight's Cup replay.
"We're underdogs, so there's no pressure on us," he said.
"We'll just go out there, get in their faces, like we did last week against them and hopefully we'll pull off a shock."
The U's are 7-1 shots to win in 90 minutes tonight with Southend 1-3 and the draw 3-1.
With Phil Trainer set to return alongside Hutchinson, Matt Day may drop back to left back.
Hutchinson hopes to do better than his last appearance at Roots Hall.
He said: "I've played there in the league a few times and got hammered. They're a decent team. The last time I played there, I got sent off.
"I know that's not good, but I'm not going to change my game. I think we're all quietly confident that we can cause an upset."
Defender Paddy Collins has returned to Darlington after his loan spell at Oxford.
The centre back made two appearances for the U's - in the 3-1 FA Cup win against Northwich and the goalless draw against Ebbsfleet - before picking up a calf injury.
