Who has Carlos Teves claimed to be a boot-l****r?

Question

In recent events, a fued has kicked up between Carlos Teves and ex team mate Gary Neville. Teves feels Neville acted like a complete boot-l****r when he said he wasn't worth £25m, just to suck up to the manager. He feels its understandable for a manager to say such a thing, but how, Neville was out of place to make such comments.
