Inter boss Simone Inzaghi was not pleased with his side's performance in their 2-1 win away from home against Lecce, saying a team with title aspirations can not be relying on a 94th-minute winner.
The Italian giants – who had the best goal difference in Serie A last season (plus 52) – opened the scoring just 81 seconds in, when loan signing Romelu Lukaku headed home Matteo Darmian's cross from point-blank range.
Inter controlled 70 per cent of the possession in the first half and appeared good value for their lead, but the entire complexion of the contest changed two minutes into the second half when Assan Ceesay tucked home his left-foot finish low and hard across Inter goalkeeper Samir Handanovic after a slick counter-attack.
The 1-1 score would hold until the game's dying moments, when an Inter corner found Lautaro Martinez's head, who flicked it on for substitute defender Denzel Dumfries to force home at the back post.
Speaking to DAZN after the win, Inzaghi said there were positives to look at, but ultimately his side needs to be more emphatic against a newly promoted team playing their first Serie A game in seven years.
"A team like ours cannot win these games [in stoppage time]," he said. "We put a lot of heart on the pitch because we won in the 94th minute, but we have to analyse the game.
"I am fortunate to have strikers who can play together like [Edin] Dzeko and Lukaku who allow us to play directly, especially on a pitch that was not in great shape at the end, with the midfielders coming in behind them. It is an option that will also be seen in the future.
"We had an excellent half hour, then we got nervous, losing the measures and conceding the equal goal. We could have scored the double before, but a team like this can't suffer so much, and you can't wait until the last moments to win."
When probed further about Lukaku, Inzaghi added: "Lukaku? I am happy, he is working hard, he is back and has a great desire and availability.
"He can improve like everyone else, but he works like everyone else. He is a driver and he will score a lot of goals from here."
