The Premier League season has got off to a flying start with a number of teams already looking like title challengers.
The two Manchester clubs - City and United, are currently leading the way.
Pep Guardiola's Citizens are top of the table with 16 points, only ahead of Jose Mourinho's Red Devils on goal difference.
City have outscored almost all of their opponents so far, netting 21 goals and conceding two. They've only failed to beat Everton, winning their other five games.
United have been equally as impressive, but haven't been as free-scoring as their rivals. Despite that, they've only failed to win one of their first six games.
Chelsea are just behind them in third, with 13 points. Antonio Conte has dragged his side back into title contention after a disappointing opening day defeat to Burnley.
Unsurprisingly, those three teams are doing so well because they have very good strikers leading the line.
The Blues signed Alvaro Morata for an initial fee of £58 million over the summer, while Mourinho spent around £75 million to bring Romelu Lukaku to Old Trafford.
Both those men have six goals already in the league and so does City's Sergio Aguero. They're the three forwards that are unplayable in England right now.
But according to legendary Arsenal striker Thierry Henry, only one of those is truly world-class. And that compliment falls to Aguero.
Speaking on Sky Sports' Monday Night Football, Henry explained exactly why he thinks the Argentine is a class above everyone else.
"The only one who is world class, or has been world class, is Aguero because of the longevity of what he has done in this league, year in and year out," he said, per the Mirror.
Suggesting that the Premier League only has one world-class striker is quite controversial because England's top division is supposed to be the envy of Europe.
But if anyone knows about being the best forward in the league it's Henry, who netted an incredible 174 league goals for the Gunners between 1999 and 2007.
