"We feel our home form has been strong and the fans have really got behind the team"
Kieran McKenna says it is vital Town continue to make Portman Road a difficult place for opposition teams to visit.
The Blues are unbeaten at home in the league since early November, with more than 20,000 fans regularly in attendance for Town's home games.
Almost 25,000 supporters backed Town under the lights against Lincoln on Tuesday, with a similar crowd expected at Portman Road for tomorrow's test with Portsmouth.
"Home form is absolutely massive," Kieran told iFollow Ipswich.
"We feel our home form has been strong and the fans have really got behind the team. It should always be a difficult place for other teams to come and play.
"We're looking forward to having that strong support again tomorrow because it has been a privilege. We know these games coming up are going to be difficult and we could be in situations where we are under pressure, or go behind, or we're looking to take the lead, and it's in those moments that the team really needs that support.
"This is the stage of the season where you need to find that extra bit of energy in games, so having a crowd of 25,000 could be what makes the difference.
"It's great to have that support and I know the fans will be there for us when we need them."
