Southampton's young interim manager has taken the step up from Under-21 manager very much in his stride. He has won three matches in a row and is favourite to be offered the permanent role at the end of this week.
The three wins under Eckert have taken on a familiar pattern with the German using the same formation (3-4-3) for each match.
Saints had to dig in and suffer significant pressure against QPR, the goals coming on the counter-attack through Jay Robinson and Léo Scienza.
Following that win at Loftus Road, Eckert made just one change (Finn Azaz for Jay Robinson) and Southampton looked even better against Sheffield Wednesday.
The interim boss has made a few brilliant tweaks
The interim boss modified the approach against Wednesday and, as a result, Ryan Manning and particularly Tom Fellows could get into more advanced positions out wide.
Caspar Jander also benefited from having the insurance of a holding midfielder (Downes/Williams) which enabled him to get into the opposition's box.
Against Charlton on Saturday, there was further improvement and the result was a thumping 5-1 away win. Saints broke faster in attacking transitions, they were patient in breaking Charlton's press, and they played through centre-forward Adam Armstrong who dropped deep to receive the ball.
Leicester's opposition analyst's will have looked at Saint's last three games and come up with a plan to nullify the approach. They will know that there is space behind the full-backs and that Southampton take risks in possession at the back. They will also know that they could get punished if their two centre-backs push out too far.
These 3 Leicester players could hurt Saints
It seems that Eckert has considered all of that and may go about things a little differently tonight. He respects the quality that Leicester have. Abdul Fatawu has led Ryan Manning a merry dance in recent meetings and Leicester have experience through midfield with Harry Winks and Oliver Skipp in the side.
Eckert told the Daily Echo, “You also have to respect that there is some quality on the other side. I think the game will look completely different to what we've seen on Saturday. We will need to be prepared to play a completely different game.“
Whether the interim manager would be so bold as to change the formation, only time will tell. You could argue the case for matching Leicester with a 4-2-3-1 but Saints don't really have the players to play that system.
At home tonight, Eckert's team might have more possession - but less space to pass the ball into. They may need to be patient on the ball and protect it a little more.
Leicester won't play into Southampton's hands and press the ball. If they do, they could be made to suffer, as Charlton did on Saturday.
