Gameplan to attack Foxes revealed
“This is the first opponent that we play that has this threat of speed in behind, and for this we have to find solutions. We are aware of what is in front of us and I think we will be prepared."
Wagner continued: "We have the chance to show we are capable and our aim is to make it as uncomfortable as possible for them.
"We know what we have to avoid to stop Leicester showing their strengths and we have to find ways of hurting them."
Wagner revealed the status of several key players:
"Kasey Palmer came back from England U21s with some problems; he had a hamstring injury and we will be out for some months." While there was good news as he confirmed "Steve Mounie got a knock but hopefully he will be back in training tomorrow.
