Lemma 11.12.3 ́. Recall that T∗ = CentG∗(A∗) is a maximal torus in G∗ defined over F ; let S∗ be the Fun-split component of T∗, a maximal Fun-split torus in G∗ defined over F and containing A∗. We have T∗ = CentG∗(A∗) = CentG∗(S∗). Choose a maximal Fun-split torus S ⊂ G which is defined over F and which contains A, and set T = CentG(S). Choose ψ0 ∈ M such that ψ0 is defined over Fun and satisfies ψ0(S) = S∗ and hence ψ0(T) = T∗.
