Lazio coach Simone Inzaghi was left frustrated after their 2-1 home defeat to Napoli.

Ciro Immobile had given Lazio the lead when taking three defenders out in one turn, but Arkadiusz Milik and Lorenzo Insigne sealed the 2-1 victory.

“It was our usual blackout," Inzaghi told DAZN.

“I don't think we deserved to lose, as it all happened in 10 minutes. We had played well and allowed Napoli practically nothing, but lacked that concentration we needed in these games.

“I'm afraid we had some players who only started training on August 2-3 and I had to use them tonight. The fixture list wasn't kind either with a difficult start, but we've got to roll our sleeves up and get to work."
