The Giallorossi had over 60 per cent possession in Tuscany and had 23 shots.
“Lukasz Skorupski put in a good performance and he's a great professional. He did his job and we didn't really do ours," Spalletti told Mediaset Premium.
“Empoli were organised and they were all tracking back to defend. The pitch also made it difficult to pass the ball around quickly and there's always the risk of getting caught on the counter.
“We have won much more difficult matches this season. We created many opportunities to score, but also missed many, plus of course Lukasz made some fine saves.
“We developed an approach with three centre-backs, but weren't good enough at passing the ball around to create the spaces."
