Manu Ginobili has said that the San Antonio Spurs must improve their record against the top sides in the NBA.

In their nine games so far against the top-five rated teams on their schedule this season, the Spurs have won just once.

The shooting guard told Express-News: "When it happens the first three times, four times, five times, then you say, 'Okay, things happen. The schedule' and now it's eight [losses], so there has to be a tendency now."

The Spurs face one of the top sides, the Oklahoma City Thunder, on Wednesday.
