Simone Inzaghi praised Inter's defending after they shut out Arsenal in the Champions League, just as they did Manchester City earlier in the competition.

A controversially awarded penalty, given for a handball against Mikel Merino and converted by Hakan Calhanoglu on the stroke of half-time, proved enough for a 1-0 victory. 

It leaves them fifth in the table after four games, one of four teams on 10 points, as they extended their unbeaten home run in the Champions League to 11 games (W9 D2), keeping nine clean sheets in this run.

What is more, Inter are one of two sides, along with Atalanta, that are yet to concede a goal in this season's Champions League. Indeed, four successive clean sheets is their longest-ever such run in the competition.

"We had a great performance, zero goals conceded to Arsenal and Man City. It's a source of great pride, but now we need to continue like this," Inzaghi said.

Arsenal had 20 goal attempts to Inter's seven but rarely looked like scoring as Inzaghi's side performed a defensive masterclass with Yann Bisseck outstanding.

"Bisseck was very good, but he doesn't have to prove anything to me," Inzaghi said. "I know how good he is, and he has played two great games against teams like City and Arsenal this season.

"His only problem is that we have other great defenders so he cannot play all the time, but I know how good he is."

Inter were under siege in the second half, facing 13 shots from the Gunners while having just one of their own. Arsenal also had 30 touches in Inter's box after the break, but the hosts' resilience kept them at bay.

"The best thing about this match is the three points, then the team spirit and the desire to fight that we put out on the pitch," Inter skipper Lautaro Martinez said.

"These matches are very important for the league table. We didn't concede any goals, and this is positive because in the [domestic] league we conceded too many.

"We must continue to raise the level. We want everything. The history of this club says so. I want to win everything."
