Southampton will be in a buoyant mood after their midweek 3-0 win over Sparta Prague in the Europa League.
Sunday’s home side did win emphatically in their first ever Europa League group stage fixture though, despite Claude Puel making seven changes from the side that lost to Arsenal.
Last week they were involved in an exciting 2-2 draw against Chelsea, where Gylfi Sigurdsson finished from the spot and Leroy Fer scored his third goal of the season.
Record signing Sofiane Boufal remains sidelined, along with Jeremy Pied and Florin Gardos with knee injuries.
Swansea’s Nathan Dyer will miss two months as he needs ankle surgery, confirmed by manager Francesco Guidolin.
The away side’s own record signing, Borja Baston, may make his debut from the bench this weekend following a thigh injury, although he has also been pictured wearing a cast on his wrist during training sessions.
How the teams could look
After making seven changes midweek, it’s expected that Southampton could revert to a similar side that have played the majority of their league games.
The shape in which Southampton looked against Sparta Prague seems near perfect to what Puel has been looking for, with a midfield diamond behind two strikers that have a lot of freedom and can drift out to the flanks if needed.
After using a common 4-2-3-1 in their opening three games, Swansea then opted to try out a 3-5-1-1 formation that only lasted 42 minutes against Chelsea.
It’s thought that the Welsh side will revert to a more familiar shape, which would give Guidolin the unenviable task of dropping one of Fer, Ki Sung-Yeung or Jack Cork.
The game kicks off at 14:05 on Sunday, at St Mary’s.
