"We know what they will do - it will be more of the same, and we have got to improve our quality in the final third," says Matthew.
"We always knew the first leg would be tight but the crowd will be an extra player - Ipswich will get a bit of a fright because the crowd will be jumping."
For Ipswich, Alun Armstrong has been added to their squad as cover for John McGreal, who continues to struggle with a slight calf strain.
If McGreal misses out, Richard Naylor will drop back to defence with Shefki Kuqi starting up front and Armstrong covering on the bench alongside Dean Bowditch.
Ipswich have not kept two successive clean sheets all season - but they have failed to score away on just four occasions - at Wigan, Crewe, Stoke and Millwall.
They have kept only six clean sheets during the 46-game league programme but only failed to score in five of them.
SQUAD: Bywater, Srnicek, Melville, Dailly, Lomas, Connolly, Hutchison, Carrick, Ferdinand, Repka, Reo-Coker, Mullins, Horlock, McAnuff, Nowland, Etherington, Deane, Zamora, Harewood, Cohen, Brevett.
