Benfica midfielder Joao Neves was happy to prove the matchwinner against Chaves.
A target for Manchester United, Neves struck with a header.
He later said: "It was a fair victory. Now in this final part of the season, after the international break, we need the support of all Benfica fans, because we still have many competitions at stake and we want to do our best in all of them.
On the header, Neves said: I try to be a very complete player, it could be me like any other player, but that's why we're there."
