Inter Milan coach Walter Mazzarri was left frustrated after their 1-0 defeat to Genoa.
It was the first time Inter had lost at Genoa in 20 years.
"I could not have asked for more from my players today. In moments when you know you're struggling and games are on a knife edge, you have to be more concentrated on set plays and more clinical in your finishing. We didn't do that," he told Sky Sport Italia.
"In these moments everything goes wrong, you have to just keep working. It's difficult to explain why we didn't score today, as we had plenty of chances and it is annoying, as we're throwing away important points recently.
"We need to keep working and find the incident that will turn the tide. Maybe we're unlucky, or maybe we are lacking sharpness, but those things are tough to fix in training.
"Considering our performances on the field, I thought we deserved a few more points, perhaps five more in the table. We'll have to keep believing in our football and our organisation until it goes our way.
"We had so many chances to score at the end and Mattia Perin was wonderful in the Genoa goal. We threw everything we had at the game, so it's hard to play more attacking than this."
