WITH the Championship playoffs due to get underway this week Saints, Leeds United, West Brom and Norwich City are all preparing themselves for their semi-finals.
As a club, Southampton only have one experience of the play-offs back in 2007 when they were beaten by Derby County in the Championship semi-final.
But who has the most playoff experience - across EFL and Scottish football - among the four squads participating?
And will it make a difference over the next 10 days?
We have taken a look through the squads to see who has the upper hand when it comes to playoff appearances at this crucial stage of the campaign.
Southampton
Playoff appearances in squad: 21
Saints boss Russell Martin captained Norwich City to Championship playoff glory during the 2014-15 season.
Current captain Jack Stephens played all three games of Swindon Town's 2014-15 League One play-off run but he was ultimately unable to take his on-loan side into the Championship, losing 4-0 to Preston North End in the final.
Joe Aribo has appeared in five playoff games with Charlton Athletic, achieving promotion from League One in 2019. He scored in the Addicks' 2-1 semi-final first-leg win over Doncaster Rovers.
Che Adams scored during his three minutes on the pitch in Sheffield United's dramatic 5-5 draw with Swindon Town. However, it was not enough to make the League One final.
Ross Stewart helped his Alloa Athletic team achieve promotion to the Scottish Championship in 2017-18 and he also scored three times for Sunderland over two campaigns.
