Real Madrid hosts Ajax on Tuesday, and Bleacher Report is taking a look at some key battles for the game.
Real Madrid are three points behind Borussia Dortmund, and even if they were to win and the Germans were to lose, they would not top the group.
That may mean a few changes in the starting lineup for Jose Mourinho's side. In their last three Champions League games, Ajax has used a 4-1-4-1 formation with Christian Eriksen leading the line.
Given the 4-1 scoreline the last time that these teams met, one can expect the Dutch side to line up like this again (via ESPN Soccernet).
Ajax is currently in third place in the group and have a lot more to play for. A win for the Dutch club would ensure that they play in the Europa League from February on.
Here are six key battles to watch for in this game between Real Madrid and Ajax.
