Boss Mick McCarthy says he expected the Blues' final day opponents Derby County to win automatic promotion rather than having to rely on winning the play-offs to reach the Premier League.
The Rams are currently fifth in the Championship but if they beat the Blues and Hull City lose at home to Rotherham will climb to fourth, which would give them home advantage in the second leg of their play-off semi-final against the Tigers.
Town can move up to seventh from their current position of eighth if they win at the iPro Stadium and Cardiff fail to beat Birmingham at home.
Alternatively, if the Blues draw with the Rams and the Bluebirds lose by five Town will go above the Welshmen on goal difference.
McCarthy says he anticipated Derby, who are unbeaten in their last six, winning four, being one of the sides going up automatically.
"I thought they would," he admitted. "When we played them here they looked like a really strong team and we gave them a real fright, but we couldn’t score against them and they nicked one and beat us 1-0. I thought they’d be the pick of the bunch, with four or five other teams.
"I was surprised when Paul Clement left, but they’ve finished on a high note. Well, up until now they’ve finished on a high note. We’ll go and try and upset the apple cart before the play-offs.”
The Rams dropped out of the play-offs on the final day last season when Town made it into sixth on goal difference, but McCarthy says that with the players they have at their disposal they should to be a top six side at the very least.
"They’ve got a helluva squad,” he said. "I couldn’t believe they finished eighth last year and with the squad that they have got and how much they have invested in it, they should be in the top six.”

The Town boss has said he’ll hand Irish U18 international midfielder Adam McDonnell, 18, his league debut and Myles Kenlock, 19, again looks set to start at left-back with Jonas Knudsen expected to miss out with a knee injury. Other than those two McCarthy will probably field a side featuring senior players.
In goal, he could bring back multi-player of the year trophy winner Bartosz Bialkowski or give Dean Gerken, the Pole’s deputy for the last few months of the season, another start.
Skipper Luke Chambers seems set to come back at right-back with Josh Emmanuel moving to the bench. Tommy Smith and Christophe Berra will again be the centre-halves.
In midfield, McDonnell could sit alongside Cole Skuse in one of the two deeper central midfield roles with either Kevin Bru or Teddy Bishop ahead of them.
Up front, David McGoldrick again looks set to start in the middle with Freddie Sears on one flank and Liam Feeney on the other.
Striker Daryl Murphy remains out of action with his calf injury and will continue his rehab back at Portman Road with manager McCarthy confident that the 33-year-old will be fit enough to make the Republic of Ireland squad for the European Championships.
Derby midfield pair Jeff Hendrick and Bradley Johnson could be back in the Rams’ squad after spells out with thigh and knee injuries respectively.
Midfielder or full-back Jamie Hanson has undergone surgery on a dislocated shoulder, which has led to Chris Baird’s recall from a loan spell at Fulham.
Left-back Craig Forsyth is on his way back after suffering an anterior cruciate knee ligament injury in early November, but is still a long way off a return to match action.
Midfielders Will Hughes and Craig Bryson were subbed late on in the 1-1 draw at Brighton and Hove Albion on Monday but with nothing more severe than cramp.
Keeper Lee Grant is over a groin injury but is likely to be on the bench with Scott Carson starting.
Derby head coach Darren Wassell is determined that his side will go into the play-offs having continued their recent good run.
"We are unbeaten in six and we certainly want to keep that mentality and the momentum of our form going,” he told Rams Player HD.
"People have talked about the advantage of having the second leg of the semi-final at home but the only real advantage that we are looking for is that we go into the play-offs as the in-form side in the division.
"That is why we want to put on a great performance against Ipswich on Saturday and try to achieve our goal.
"We want to remain unbeaten at home and really create a fortress at the iPro Stadium. Our home form has been really pleasing and we want to keep it going.
"We know that this game isn’t the end of the season because we’ve got two, hopefully three, really important games coming up.
"We can’t treat it as the end of the season, we have to approach it with the mentality that we are going into the play-offs firing on all cylinders.”
Historically, Town have had the better of Derby, winning 33 games (31 in the league), drawing 21 (19) and losing 26 (25).
In December at Portman Road, Tom Ince’s 40th minute goal saw Derby County to a 1-0 victory.
Town took the game to the Rams in the second half but rarely looked like getting on terms with the visitors, who climbed to second as a result of their victory.
Last time the teams met at the iPro Stadium, in August 2014, Christophe Berra nodded home his third goal of the season to secure the Blues a deserved point as the game ended 1-1.
The Scotland international headed in Paul Anderson's freekick on 52 to level Chris Martin's 13th minute goal for the Rams.
Former Blues striker Darren Bent joined the Rams last summer following a loan spell in the second half of last season.
The 32-year-old came through the academy ranks at Playford Road and went on to make 116 starts and 25 sub appearances for the first team, scoring 55 goals, between 2001 and 2005 before moving on to then-Premier League Charlton.
Bent has been something of a bit-part player for Derby this season, scoring three goals in six starts - only four in the league - and 16 sub appearances.
In addition to Bent, Rams centre-half and skipper Richard Keogh was an academy schoolboy and Portman Road ballboy during his formative years.
Luke Varney was with Derby from November 2008 to July 2011, initially on loan from Charlton, but made only 11 starts and four sub appearances, scoring one goal, spending much of his time with the Rams out on loan.
Blues loanee Ben Pringle was with the Rams between July 2009 and June 2011, making seven starts and 16 sub appearances without scoring.
Town keeper-coach Malcolm Webster held a similar position at Derby under George Burley's spell in charge of the Rams.
Saturday’s referee is Tim Robinson from West Sussex, who has shown 139 yellow cards and nine red in 41 games so far this season.
Robinson’s most recent Town match was the 2-1 home victory over Reading in February in which he booked Christophe Berra and two visiting players.
Robinson’s only other competitive Town game was the 2-0 home defeat to Middlesbrough in December in which he again yellow-carded Berra and two visitors.
"Prior to that he took charge of the pre-season friendly at Crawley in the summer of 2013 in which he awarded the Blues a penalty, which was converted by David McGoldrick in a 2-1 victory.
Squad from: Bialkowski, Gerken, Chambers (c), Knudsen, Foley, Emmanuel, Kenlock, Berra, Smith, Digby, Skuse, Hyam, Douglas, McDonnell, Bru, Bishop, Feeney, Maitland-Niles, Sears, Pitman, McGoldrick.
