I had way less tolerance for Rooney's roaming during the Koeman free-for-all than I do now. When the ball was sailing over his head repeatedly, it didn't make a whole lot of sense to accommodate him, especially given his physical decline.
With an actual plan in possession, we need Rooney on the pitch. He's our best passer and the player most likely to make something happen from open play. You saw it against Chelsea. When Unsworth took him off, it really loosened our grip on the game and allowed Chelsea to breathe a bit.
