Napoli have proved that they are a side to be respected after their draw at Manchester City, says Gokhan Inler.
The Azzurri collected a vital 1-1 away draw in the Champions League on Wednesday in a group that also contains Bayern Munich and Villarreal.
"We showed we're a strong team defensively and a young team that wants to do well," Inler told uefa.com.
"We played away from home and got a point," added the summer signing from Udinese.
"But every game will be difficult and we have to play them and see where we are after the six games."
Napoli took the lead through Edinson Cavani before former Lazio man Aleksandar Kolarov equalised with a free-kick.
"It was a very important result because this group is very tough and every point is vital," the Swiss international added.
"We know that at home City press very well and are strong, but we were well organised in defence and counter-attacked well in the second half."
Napoli are next in action in Europe's premier club competition at home to Villarreal, who lost 2-0 to Bayern last night, on 27 September.
