I don't like to underestimate teams in case they make us look like turd, but in this case I can't see anything other than a Saints victory. All the work put in during the recent weeks, and the strengthening and belief that now exists will show on Saturday and I'd be very suprised (and annoyed as I'm having a flutter on Saints) if we don't win by more than 2 goals.
Lambert has struggled to score in the last couple of games, but now we have left midfielders rather than an out-of-position Lallana, he'll get the service he desires and will score a couple.
