The only player that "switched" numbers was Cavani. When James left for Leeds the 21 number became available so we switched it to Cavani because it's his preferred number.
This let the number 7 free which has now gone to Ronaldo since he had not been assigned a number (as far as i know).
And yes, United are sorting out supporters who bought new shirts with Cavani 7 on them by exchanging them at the club shop.
There you go then, shouldn’t be an issue.
