Leicester's 1-0 defeat left Atletico in charge of the tie ahead of Tuesday's return leg, but with Vardy now back among the goals, his team-mates hope more memorable milestones are ahead.
Craig Shakespeare must decide whether to focus on securing Leicester's Premier League survival against Crystal Palace or allow his stars to rest before the latest chapter in their European adventure.
The situation wasn't helped when Younes Benalouane was withdrawn during Saturday's 2-2 draw at Crystal Palace in the Premier League, per Sami Mokbel of the Daily Mail.
After only seven minutes Fuchs delivered a bomb of a ball into the Palace box and it so unnerved them that Robert Huth was able to head past goalkeeper Wayne Hennessey.

"He was a player I had a lot of time for". The pressure is constant and no one day is the same, but I don't like to eat the same thing for breakfast every day so that suits me. We need to make sure that we create more, but we also need to be mindful of their players. The same as 2-1 was away from home in Seville - we're looking forward to it and we'll be ready.
Last season, they wrote the first chapter of their outstanding story by winning the English Premier League (EPL) for the first time in the club's history.
