We also have to get away from City and Liverpool too.
They have got 2 of the most expensively assembled squads in the history of football in terms of wages. They have 2 of the best coaches in the world, who have both been given years to implement specific styles for their respective clubs. They also both have very specific game plans that would be very hard to emulate, even if you had the same level of resources, time and knowhow.
Liverpool still at times operate with a target man too. Origi would do it in bursts, and Nunez is a target man too. No surprise Klopp loses Origi and adds Nunez. You know, Haaland is a target man too. He can do lots of the other stuff Pep likes, but he is a target man.
For the rest of the league, a player like DCL is important. I honestly cant see any sense in not using him, because of what Liverpool or City do. We are not either of them. If we tried to be, it would all end up like Martinez.
