I wanted to get back to the Premier League from what Ive done for Blackburn, so Im over the moon.Saints boss Ralph Hasenhuttl added: Adam was a big target for us this summer, so we are very pleased to have added him to the squad, especially as there was a lot of interest in him from other clubs too.He will bring a lot of qualities to our team, and he gives us another good option in attack, which will be important for us.
