The Whites have two games of their 2020/21 campaign left to go, and look set to secure a top-half finish after a stellar return to top tier football this season.
Speaking ahead of tonight's match, Saints boss Ralph Hasenhuttl reflected on Leeds' success this season, and said: “It is not that surprising, to be honest. I know how it feels to be promoted and have a good first season in the big league, I had it with Ingolstadt and I had it with Leipzig.
“The team is always super motivated, the players, it's a completely new experience when they get the chance to finally compete with the big ones. That carries you beyond those tired moments, past the tough moments.
“Leeds have had a few games where they have struggled this season but they have shown that, especially against the big sides, they can show very good performances.
“This was surprising, that they could compete like that against the strong sides in the league. They haven't lost a lot over the last weeks so they are getting better and better.”
Meanwhile, down in the Championship, it was a disappointing evening for Barnsley last night, who suffered a 1-0 home defeat to Swansea City in their play-off semi-final first-leg at Oakwell.
