I think he'll play Rhys Williams alongside Fab. Saints like to press as we know but Williams is solid technically and has proven to be comfortable on the ball. I hope Thiago starts in midfield with Henderson and Gini. If they do press us in midfield he is so comfortable in tight space and can take the ball on the half-turn and release Salah or Mane. Similarly Gini is very good with bodies around him, he has quick feet and he is nimble.
Really interested to see if they get after us or whether they sit and pick their moments to press, i think the latter is more likely BUT Saints evidently have pressed the ball more than any other epl team this year.
It's usually a touch game at St Marys but i can see a 2-1 win, Salah and Mane with the goals.
