Atalanta coach Gian Piero Gasperini was happy with their 2-0 win against Genoa.
Ademola Lookman and Ederson struck the second-half goals.
Gasperini said: "I am satisfied with the match we played against a very difficult team. To win we had to play with quality and patience, without exposing ourselves to their counterattack which is very dangerous.
"We broke the deadlock, we had several chances before. I think the result is right, but it was tough.
"Today was a match to be taken with a pinch of salt, there was always the risk of being surprised, we had to be very precise. Many teams, even famous ones, suffered certain situations against Genoa.
"If anything less, we are beyond expectations. I didn't expect a start with so many points, it's a balanced championship. I'm sorry for some games lost at the end that we could not have lost, this took away the possibility of still having a better ranking. But we have a top ranking, we had a really high performance and we hope to continue like this."
