In his pre-match press conference on Thursday, Southampton boss Ralph Hasenhuttl confirmed that Moussa Djenepo has returned from injury and is available for selection once again.

The eight-cap Mali international hasn't started since the 1-0 win over Sheffield United on the 14th September, a game in which he scored the winner - his effort was later named as the Goal of the Month.

Djenepo - signed for £15m back in the summer - made his long-awaited return last time out against Manchester City, playing the final six minutes of the 2-1 defeat.

With the former Standard Liege attacker - who has two league goals in four appearances this term - now fully fit again, here are two things that need to happen against Everton on Saturday.

Change the formation

Against the Citizens last time out, Hasenhuttl adopted a heavily defensive 5-3-2 formation.

There was nothing wrong with doing that against the back-to-back Premier League champions, but against Everton - a side who are just three points above the Saints in 17th - Hasenhuttl must be more attacking.

In that respect, a switch to a 4-2-2-2 formation, or a 4-3-3 system, absolutely must happen - especially with such a potent attacker in Djenepo now back and ready to play.

Drop Jannik Vestergaard

If Hasenhuttl is going to be more attacking, then he needs to drop a member of the back-five who started at the Etihad Stadium.

Jack Stephens has been performing well lately and was exceptional against City, whilst Jan Bednarek is one of the Saints' better defenders, so £18m man Jannik Vestergaard should be the one to drop out to make way for Djenepo's return to the XI.

The 6 foot 6 centre-back did make a game-high 18 clearances in what was a backs-to-the-wall showing against City, although with Everton being an easier opponent on paper, Hasenhuttl shouldn't be setting his side up to simply clear everything that comes their way.
