Adam Lallana: “I have got four years or so left on my contract. I can’t express how happy I am at the club. I am so settled. Settled at home with a young child and my family live down here." "I don’t think I am too comfortable either, I get challenged week in week out playing in the Premier League. It is where you want to be as a player." "I learnt my trade in League One and the Championship and feel I have grown with the club. I am delighted and as happy as I have ever been here playing for Southampton with one of the best managers in the league. I have been here nearly 13 and-a-half years.” http://www.mirror.co.uk/sport/football/transfer-news/manchester-united-transfer-news-adam-2964994 DTLW
New article no doubt, but the quotes are old. Like MMJ said, he said those to Jim Lucas in an interview at his home for Saints player.
Doesn't matter...Adam won't have changed his mind in the last few weeks. For all we know, the club PR team may have directed the media to the previous article.
