Man Utd icon Rooney seen at Wigan vs Hull supporting ex-Derby assistant RoseniorSaints were bossing the midfield. Stuart Armstrong had the freedom of the park. Ipswich were hit by the blow of losing striker Kieffer Moore after just 36 minutes.
But anyone who writes off this Ipswich team does so with their peril.
Boss Kieran McKenna once again showed why he is quickly establishing himself as one of the brightest coaches in English football right now.
He made a triple change on the hour bringing on Jack Taylor, Harry Clarke and Nathan Broadhead.
And two of them combined to bring Ipswich level with Taylorâs wonderful pass finding Broadhead and in one swoop he swivelled and struck the ball through the legs of a defender and past Bazunu.
With five minutes left Davis was played in but Bree hauled him down and ref Michael Salisbury duly produced a red card.

And the Ipswich boss said: âIt was right up there with the best games since Iâve been here.
âIt was another brilliant match to be involved in and to win it in the last minute, itâs a moment to really cherish.
âWe kept out calm at half-time and just needed to regroup â and then the subs have done their job. Thatâs why these players are there â you need quality on the bench to win games like this.
âThis has been one of the toughest games to prepare for because Southampton cause so many problems.
âIâve almost forgotten what sleep is these past few days â but when you get a day like this it makes it all worthwhile.â Earlier Sam Morsyâs lovely raking ball found Davis on the left edge of the box.

But within the blink of an eye Saints were back level.
Adam Armstrong crossed from the right and Joe Aribo burst forward to get on the end of it.
The ball broke for Adam to score a typical poacherâs goal from six yards.
Ipswich were appealing for offside but Cameron Burgess was playing everyone on.
Here's how the match played out on paperAnd, incredibly, Saints moved into a 23rd-minute lead with a goal of sheer quality.
Bazunu taking possession to the ball being in the back of the net took just five touches.
Stuart Armstrong threaded a beautiful angled pass that dissected the Ipswich defence and caught Davis slightly out of position.
And Adam Armstrong ran on to it to drive a low effort into the bottom left.
Russell Martin refused to accept his fourth-placed Saints defeat and he said: âWe were the best team and didn't deserve to lose.
âWe had 17 shots on goal, had five huge chances and missed three. They had relatively little until late on.
âWe were the dominant team and shouldâve gone on to win the game. Even when we were down to 10 men, we missed a great chance and they scored theirs.
âSo I'm proud of the players. It was a brilliant performance and if played like that between now and the end of the season, we'll still have a chance of automatic promotion."
