We consider the Monge problem in a convex bounded subset of $\mathbb{R}^d$. The cost is given by a general norm, and we prove the existence of an optimal transport map under the classical assumption that the first marginal is absolutely continuous with respect to the Lebesgue measure. The approach we propose to solve this problem does not use the disintegration of measures.

Keywords: Monge-Kantorovich problem, optimal transport problem, cyclical monotonicity
