Xavi and Iniesta, Iniesta and Xavi

For Barcelona, Xavi Hernández wears the number 6, while Andrés Iniesta is 8.

At international level, however, before Xavi’s retirement it was the other way round. Answers on a postcard, please.

Edit: Thanks to journalist Michael Cox (@Zonal_Marking) for informing us that, apparently both wanted 6 at Barcelona and so Xavi allowed Iniesta to wear it for Spain.
