Leicester City boss Nigel Pearson admitted frustration after the winter market shut.
The Foxes picked up keeper Mark Schwarzer, defender Robert Huth and striker Andrej Kramaric in the January transfer window.
But Pearson wanted more and said: "We'd talked about doing business early and the potential targets we had late in the window were not doable.
"I'd rather not be involved in really late deals. Sometimes you can't avoid it.
"It was pretty clear early in the day we could not achieve our targets.
"I'm pleased with Mark Schwarzer and Robert Huth coming in for their experience and hopeful Andrej will fulfil his potential with us.
"It was important we brought in quality. We have also complimented what we already had."
