Last Saturday, Watford boss Quique Sanchez Flores said he had just seen the best side in the Premier League. Earlier, his players had been pressed and harried so relentlessly that they had not mustered a single shot on target. What Watford had lacked, explained Flores, was not a clear game plan, but rather a chance to execute it. "We know perfectly what we want to do when we recuperated the ball, we try to play," he said. "But it was impossible."
