#1 Isco - Real Madrid
It would be highly unlikely to sign a player like Isco, as with his €700million buyout clause, Real Madrid has proven a point; they would rather keep Isco with them than sell him. However, the ongoing situation at the Santiago Bernabeu could make him leave the Spanish capital and move to some other club. Manchester City is the kind of club that would be ready to spend it all and have his signature.
The Spaniard has been on Guardiola's watch ever since he was at Malaga, and is still somewhere on his radar. With the arrival of one of the most consistent attacking midfielders in the world, Man City will only turn themselves into one of the most dominant clubs in all of Europe. The fact that they have one of the most dominant attacking lineups can be something that can create a revelation in football.
