Sometimes there are those days when everything just seems to drop into place. Those who need a goal are confident and clinical, those paid to keep them out are focused and alert; and Aston Villa are in town. Theo Walcott invited ninth-month-old son Finley along to his first game and was able to mark the occasion with his first goal in the Barclays Premier League for more than a year. 'In the second half, I can't think of a more one-sided game,' said Walcott, swept up in the euphoria of a fifth successive win, and the joy of being fit.
