They are good players but prising them out of Germany would be protracted and expensive. Camavinga is good, though perhaps not best suited to our style of play, and with a contract to 2029 he is off the table.
They are all prospects but, like those above, untried in the League and physically some are better suited for the flanks. Similarly, the importance of our keeping Grealish on the left is becoming clearer with each game.
As evidenced in key games, we have an energy problem in the centre of midfield, and in two summers have spent £120 million on Phillips/Nunes/Kovacic for a grand total this season of: 318; 1,240; and 2,172 minutes, respectively. Rodri is just shy of their combined total with 3,498. While I'm all in favour of giving Lewis and Bobb more game time, we need someone in the middle of the park with more experience and muscle, particularly if Bernardo leaves. It's also vital that Guardiola has complete faith in them.
Paqueta would be expensive, but probably £35 million cheaper than he might have cost last summer, and when surrounded by better players, as he is with Brazil (no disrespect to West Ham), he will excel.
