Mathieu Christian Moreau (born 22 February 1983) is a French former footballer who played as a goalkeeper.
But, along with Paolo Castelli, who was also owned by Inter, he failed to play regularly, being behind Brunner, and later Massimo Gazzoli, in the pecking order.
He quickly became the first choice goalkeeper, and won 2009 Lega Pro Seconda Divisione.
In the next season, Varese finished in second place of the Lega Pro Prima Divisione, as well as winning the promotion playoffs.
After the departure of Zappino in late August 2011, Moreau became first choice again in the first four rounds - with zero wins, two draws and two losses.
