Erling Haaland may struggle to score as many goals over the rest of the season as opponents figure him out, says former Manchester City defender Nedum Onuoha.

The Norway international has enjoyed a blistering start to life at the Etihad Stadium, with 23 goals across all competitions since arriving from Borussia Dortmund.

That includes 18 in the Premier League alone, putting him firmly on course to smash the competition's record single-season tally of 34 with not even half the campaign gone.

But while Onuoha, who played for City between 2004 and 2012, thinks it likely he could rack up an all-time feat, he warns the Leeds-born attacker will likely face sterner opposition following the mid-season break.

"It's very possible," he told Stats Perform. "But I think it gets harder the more time that passes in terms of being in the league, because people know how you operate.

"They know they have to have get a better idea of how to stop you, because City with a six-foot four striker is a different look for most teams that played against them for the last six or seven years under [Pep] Guardiola.

"It's possible if he stays available and City stay dominant. But football is very difficult, especially in the second half of [a] season, where you start to run out of time.

"The moment you start running out of time, the desperation kicks in, and things which maybe would have been easier in the first half of the season [are] a bit more difficult."

Onuoha feels Haaland has shown he can cope with the pressure amid a lightning start, firing City into the thick of another title race, though the ex-defender also praised Arsenal amid their own surprise charge

"There's going to be so many more eyes on him because he [is] one of the biggest players in world football, not necessarily the Premier League," he added. "He's a talent who's going to bring eyeballs. He's been exceptional.

"But I have to give credit to Arsenal, I think Arsenal has been incredible. They've dropped five points up to this moment. And in those games, they've looked really good.

"It's very entertaining. Whatever we see now, there's no guarantee this is how it will finish. I think that's what makes it so special."
