Latics stunned npower Championship outfit Nottingham Forest with a 3-2 comeback win earlier this month and were rewarded with another crack at the Reds, who fell a goal behind before beating Dickov's men 5-1 in round three last season.
A step closer to Wembley this time around, life-long Liverpool fan James Wesolowski is set to captain Oldham in the absence of fellow midfielder Dean Furman, who is away with South Africa in the African Nations Cup.
Winger Cristian Montano (thigh) remains the only injury absentee, as was the case when Latics slumped to a seventh defeat in eight npower League One matches at Notts County in midweek.
"We'll have the same squad as we had the other night," said Dickov. "Jim's obviously back in, Cristian's still out, Dean's away so we'll go with what we've got."
Youngsters Daniel Taylor and Craig Sutherland were handed their first senior starts against County but are expected to revert to the bench.
