The Reds head coach previewed the last-eight encounter at St Mary's during a session with reporters on Tuesday morning.
See what Slot had to say with the following summary…
**On serving a touchline ban for the game and how much it will impact him...**
Not as much as I thought it should impact because if you are suspended in Holland then you are not allowed to be in and around the dressing room, you cannot do the media as well. So, this is a lighter version of suspension I would say that I'm used to but I've never been used to being suspended, so it's the first time I am. I think I'm still able to do the things I want to do. The moment you have the less impact on your team is during the 45 minutes. And the most impact you can have is at half-time or before the game – and those are the things I can do. But in an ideal situation, I would have just been on the sideline. But I got a yellow, which I probably deserved again as well, and it happens.
**On what to expect from Southampton after they parted company with Russell Martin...**
It's difficult because I saw them during the weekend starting with four at the back, which they changed after 15 minutes, going to five at the back. And the one that takes over normally plays with four at the back, so what can you expect? I think the players maybe feel more comfortable with five from what I saw during the weekend. But it's also a moment for the manager to have his impact. If he truly believes four is the best… and it depends maybe also on how long is he going to get. Is he only there for one game or is he there for longer? Will he play with his normal starters if he only has one chance or a few chances to lead the team? Will he then do what's best for the Premier League or for him as a chance to maybe reach the semi-final of the League Cup? So, it's difficult what we can expect in terms of formation, in terms of personnel. But what we do know is that we have to play an away game against Southampton, against 11 players.
