Simeone would be a dream choice.
Perfect fit for the club given his time at a similar club with similar constraints but unlike Pochettinho actually delivers major honours. I also think his time at A. Madrid has run its course and he needs a new challenge.
As for not being able to attract him - Jesus some of our supporters are so small time. I heard exactly the same with Ramos when we in a far weaker position than now. And if a mid table mediocre Liverpool side can attract Klopp there is no reason we couldn’t do the same.
We can attract the likes of Ancelotti, Simeone and even Conte ( If we made a move in the summer).
Their salary may be the problem
What about Potter from Brighton?
With a DOF
