Now do the same top but for all competitions + NTs for the last 3 and a half years..and you may have a surprise.
Don't have those stats available to me
I'm sure he's very high up. I'm also sure Ronaldo, Rooney, and all the other mentioned names are as well. Physically, players can deal with this.
That said, I agree the mental strain is great, and combined with the NT issues he's probably had more than enough stress. Probably puts himself under immense pressure too. A good long holiday would be fantastic for him.
And part of me hopes we lose a couple games so we can just rest these guys. Xavi, Iniesta, Messi, all of them need a good proper break.
