“I know what I’m doing, but it’ll just cause chaos if I say anything.

“All I’m thinking about now is finishing this season off strong and we meet up straight away for the Euros.

“I’m not thinking about anything else other than Wales.”

Staying at Real Madrid ...
Signing for Tottenham ...
Playing in Premier League / MLS / far east ...

None of the above would arguably be causing chaos.

Signing for Cardiff ?

This would cause chaos for Bluebirds fans with season tickets currently unavailable?

Fights breaking out in ticket queues for the 10000 or so made available for each home game.

Championship rivals (including our cousins down west) claiming 'it's so unfair', and sending a petition to Boris asking for CCFC to be expelled from the English pyramid.
