Sergio Aguero has waxed poetic about former Manchester City teammate Gabriel Jesus following his spectacular start to life at Arsenal, but he is concerned about the Gunners’ season as a whole.

The Gunners paid £45 million to lure the Brazilian to the Emirates in the summer, and it has since proven to be a wise investment, as Jesus has breathed new life into what was a dormant front line last season.

This season, the ex-Etihad favourite has five league goals from the first nine games.

Jesus appears to be thriving given that he is no longer in Aguero’s shadow, as he was at City, when he struggled to ever completely displace the Argentine as first-choice striker for an extended length of time.

That’s not to suggest there is any ill feeling between the two. In fact, Aguero has heaped praise on his old colleague.

Speaking to Stake.com, the five-time Premier League winner and City legend said: “Gabriel has always had good respect, he’s truly a complete player. Now, he’s been able to secure a place among the main squad for Arsenal, and his team has many young players with a hunger for glory.

“[Mikel] Arteta has really been able to imbue it with his style. This has all set up Gabriel to be a key piece of the team, and I’m very happy for it.”

Jesus has been instrumental in Arsenal’s amazing start to the season, with the Gunners sitting atop the Premier League standings, one point clear of his former club as Pep Guardiola’s City close in.

The atmosphere at the Emirates is currently at an all-time high, with morale across the stadium sky-high as a result of Arsenal’s flawless play.

The Gunners’ 3-2 triumph over Liverpool on Sunday was quite a statement, given that they had previously failed to defeat Jurgen Klopp’s team.

Despite this, Aguero still harbours some fears for Arsenal over the course of the whole season due to the World Cup interrupting the Premier League schedule from November until late December.

“We’re on the first stage of a Premier League that will be different from many others – by and large because we’ll have a World Cup in the middle of it. That makes it harder to foresee how it’ll turn out,” Aguero explained.

“Consistency is the name of the game to win the title and the missing piece is knowing in what condition each player will rejoin their clubs after the World Cup.

“Arsenal will probably be one of those teams but surely not the only one.”
