“It was a great comeback match for him, his ball control shone through today,” said Spalletti.
Inter’s 2-0 San Siro win came in the absence of Mauro Icardi, Ivan Perisic and Marcelo Brozovic.
But Candreva believes it can bolster their faint Champions League qualifying hopes.
“It was a positive performance from us that shows we’re still in it. Now, for the Champions League, we have to put the pressure on ourselves,” he told Sky.
“We will try to win all our remaining games.”
Argentine striker Icardi and Perisic were handed two and one-game bans respectively following unsavoury incidents at the end of last week’s 1-0 defeat at Juventus, where Brozovic broke his toe in a challenge with Miralem Pjanic.
Given Icardi and Perisic have scored 22 of Inter’s 37 league goals this season, Nerazzurri fans had cause for concern.
But any pre-match fears were settled quickly, Empoli ‘keeper Lukasz Skorupski performing heroics to tip a Rodrigo Palacio header out from underneath the bar early on.
Inter broke deadlock in the 14th minute, Eder chesting the ball past Skorupski at the back post after Palacio flicked on Candreva’s inswinger.
Eder turned provider 10 minutes after the restart, the Brazil-born Italy striker setting up Candreva for a strike from distance that beat Skorupski at his near post.
