Tuilagi, who has been named in the England’s Rugby World Cup squad, scored a try in their sensational 57-15 win over Ireland.
Fly-half George Ford said Tuilagi has been progressing well in his performance leading up to the world cup.
“Manu had some good continuity. You’re seeing some good things from him but I honestly do believe he is still getting better and building as well. He’s going to be unbelievable for us, he has got a massive smile on his face and he’s loving it at the minute.”
