The Leeds boss wasn't happy with the Italian - or his side as a whole.
The Whites took an early lead through Souleymane Doukara - but two goals from the hosts subjected Leeds to their first defeat in some weeks.
And Evans was unhappy with several areas of his side's display - including goalkeeper Marco Silvestri's distribution.
The Scot told BBC Radio Leeds: "We had individuals who decided they wanted to attack, rather than get possession. Leeds United supporters will be thinking we need to get some better players.
"The whole thing was wrong after twenty minutes. Marco’s distribution was all over the place, we were never high enough up the pitch and everything was a problem.
"We need to get some quality into this football club. We are trying to sign them but it's frustrating."
Evans is right to be annoyed but it's important to remember the fact Leeds were unbeaten for several games heading into this clash, while Ipswich are currently in the play-off places.
Of course, the manner of the performance won't please anyone associated with United - and the fact they need to bring quality in during the transfer window is clear for all to see.
The issue with Silvestri, however, is one that the Leeds boss needs to take responsibility for, too. Uwe Rosler kept insisting on sticking with the Italian, while Evans has also backed him.
As a shot stopper, he has undeniable talent. But, in terms of distribution and aerial handling, Silvestri has needed work for some time. It's up to Evans as Leeds' head coach to address that.
