Saints aim to win at Goodison for the first time in 18 years and they won't have a better chance to do so.
Saints travel to Merseyside as one of the form sides since the turn of the year with only Leicester and Tottenham amassing more points, in contrast Everton are barely above the bottom three in this medium term form table.
Add to that the fact the Toffees not only have a big match with Liverpool in midweek after the Saints game followed by an FA Cup semi final date with Manchester United and it's easy to hope that they will have their eyes on more important games that the visit of Saints.
They are also suffering from injury and suspension problems with at least four set to miss out through injury and another suspended, meaning half their team will be out and perhaps more if Martinez decides to rest others.
That gives Saints the ideal opportunity to go to Goodison and return with all three points, the downside is we will have to do it without Charlie Austin, but Steven Davis returns and we can recall Juanmi to the bench.
So we should head to the North West with confidence, we need to do what we do well and that is breaking at speed and harassing their defence with the pace of Long and Mane not to mention the in form Pelle.
It's a vital game for Saints, due to our early season slip ups we are playing catch up, but there is no reason why we should not win at Everton and then at Villa a week later, but one game at a time and lets get this one under our belts.
Teamwise i expect Steven Davis to return in midfield with the key possible changes for Koeman being Soares for Martina, Romeu for Clasie and Davis for Tadic.
So for me starting line up
Forster
Soares, Fonte, Van Dijk, Bertrand
Mane, Wanyama, Romeu, Davis, Long
Pelle
Subs Steklenburg, Martina, Targett, Rodriguez, Tadic, Juanmi, Clasie
Good strong team with good choices off the bench.
