(Reuters) - Billy Vunipola believes England have the mental strength to carry the weight of expectations as they set their sights on a second successive Six Nations grand slam with a win against Ireland on Saturday.
England thrashed Scotland 61-21 last weekend to secure back-to-back titles and victory over Ireland at Dublin would see them win all five games in the championship for the second year in a row and set a tier-one record of 19 consecutive victories.
