We would get absolutely battered man. 90% of this squad was in League One last season, we scraped into the play-offs on the final day, and if we did make the play-off final, we'd be underdogs. Meanwhile Newcastle are third in the league, with literally unlimited money and are by some margin, the richest club in the world. Anything less than absolute domination of the league by 2030 is a failure for Newcastle.
You don't understand football.
