A win over Manchester City on Sunday would be just another stepping stone in Manchester United’s path toward the 2015-16 English Premier League title, according to United manager Louis van Gaal. “Ifwe beat Manchester City,” the Dutchman said, “we are first in the table but that doesn’t mean we are the champions. The championship is decided in May. It’s a big step when we win that’s true but youalso have to continue. That’s also a big question.”
