Erling Haaland could become the greatest player in Premier League history after making an astonishing start to his Manchester City career, according to Jamie Carragher.

Haaland has been in electrifying form for Pep Guardiola's champions since arriving from Borussia Dortmund, hitting nine goals in his first five league appearances for City.

That haul is the best managed by any player in their first five Premier League outings, and the towering Norwegian became the first player since Harry Kane in December 2017 to score back-to-back hat-tricks in the competition against Nottingham Forest on Wednesday.

The City striker has averaged a goal every 43 minutes of league action this season, and Carragher believes Premier League fans are witnessing something special.

"I'd probably say Man City have had a really good window, with the players they've brought in," he told Sky Sports.

"They lost a lot of attacking players, but you look at Haaland… [Julian] Alvarez's start already, he looks [to have] real quality.

"Haaland's the one that jumps out at you, he just looks absolutely amazing.

"We know we've got a great player in the league, but I think we've got something really, really, special, where when he's finished his time at Man City or in the Premier League, we'll be taking about him alongside Thierry Henry.

"I think this lad could end up being the best player we've seen in the Premier League, I really do. He's that special and he's made a brilliant start."

Should Haaland find the net when City travel to Aston Villa on Saturday, he would become just the fifth player to score in his first three away Premier League games (after Peter Beardsley, Jurgen Klinsmann, Francesco Baiano and Alen Boksic).

Given the 22-year-old's incredible form, he will likely also have his eye on becoming the first player in the competition's history to score a hat-trick in three consecutive appearances.

Pierre-Emerick Aubameyang is another former Dortmund striker to have made a Premier League move, reuniting with former BVB boss Thomas Tuchel by swapping Barcelona for Chelsea.

While the 33-year-old's time at Arsenal ended in acrimonious fashion in January, Carragher believes his arrival represents a welcome boost for Chelsea.

"He's a quality player, there's no doubt about that, and I think it's a good signing," he said.

"People may question Arsenal's role for this, the fact they've let him go for free and Chelsea are paying money for him [less than] 12 months later.

"I think it's a good signing for Chelsea, but I also think it was the right decision for Mikel Arteta and Arsenal, look where they are right now.

"Aubameyang, we know what he brings, goals and quality. Thomas Tuchel knows him, he's worked with him at Borussia Dortmund as well, and as a neutral, I'm delighted he's in the Premier League. He's a brilliant player."
