Como dizer "ele disse para você ligar mais tarde" em inglês

Pensei em:

"He told you to call [him] later"

Outros poderão oferecer outras sugestões.

Só para acrescentar:

He asks you to call him later
He asked you to call him later

He asks to call him later. (it suggests that he needs your calling, he is interested etc, so he "asks")
He asked you to call him later. (the above also suggests "hot news" and this one would mean that I went to him and I am back to you.)
Both can used almost interchangeably in many situations, though.

He said you can call him later. (he just said.)
He said you shall call him later. (you need to call him later, just call later.)

He said you can ring him later. (a bit slangy.)
He asked you to ring him later. (a bit slangy as well.)

De fato, as 343.000 instâncias da estrutura "he said for you to" no Google fazem dela uma estrutura bastante comum e encontradiça no inglês informal. Tentei encontrar a diferença entre "said for you to" e "asked you" (uma estrutura possível) em sites de gramática e eu só não encontrei a diferença, como também não encontrei nenhum site.

Mais sobre a estrutura "say for":

Many native AmE and BrE speakers naturally and commonly use it in colloquial speech. A conjunction of grammarians, however, will not consider it acceptable in more formal contexts.
