I'm not being horrible mate,but he has a similar goal return to Rashford, and offers a lot more in the broad attributes (being at the same age as Rashford too).
There are criticisms of Calvert Lewin, but some of them verge on the ridiculous and don't stand up to scrutiny. The idea he's a championship player is one of those.
You talk about teams 4-6, well last season against the teams who finished 3rd, 5th and 6th he was miles ahead of any of their strikers. One of who'm has just been sold for £70+ million.
