"The players know they're going to have to work hard to win this title. But we've got a good squad and I think we're improving in certain aspects of our play."
Sir Alex was particularly pleased with United's defensive display as a unit at the Madejski Stadium.
"We had to work really hard and defend as a group," he observed. "There's a good understanding of the importance of the defensive part of our game and we're better than we were last season in that sense."
