Southampton boss Ralph Hasenhuttl is looking forward to a tactical battle with Liverpool rival Jurgen Klopp tonight.
The pair, born seven weeks apart in the summer of 1967, took their coaching badges together.
"It's the first time we play against a very good pressing team and the style of football I prefer," said Hasenhuttl.
"You can see this team is one step or two steps ahead in their development.
"It will be a very interesting game for the coaches for both sides and we will have to do a lot of work with coaching the team. It is maybe a big challenge but I like this challenge."
