James and Rashford are machines. They just keep on going. Martial has injury issues so we need a second nr 9.
I have seen most of Haaland's matches and he's old school. No bullshit, no special shot or technical, just an old fashion goal scorer.
With James crosses he will always be in front of the goal. This is something Ole and Martial have worked with but still Martial is not near the goal when there is a cross.
Haaland will be there and will score many simple goals. His also much faster than what people think, his top speed is same as James.
