I am looking for a reference to the following statement. (It should be known --- I saw it before, don't remember where; search by keywords did not help.)

Let $f\colon M\to N$ be a homeomorphism between two smooth $d$-dimensional manifolds. Suppose that $M$ and $N$ admit Riemannian metrics such that the $f$ is $e^{\mp\varepsilon}$-bi-Lipschitz for some $\varepsilon=\varepsilon(d)$. Then $M$ is diffeomorphic to $N$.
