Real Madrid host Bundesliga giants Borussia Dortmund on Wednesday night, with top spot in the group still up for grabs.
Here is the potential lineup for the match...
Costa Rica goalkeeper Keylor Navas is most likely to start, with the ex-Levante keeper looking for his third clean sheet in this year's competition.

Right-back Dani Carvajal is suspended for the game, after he picked up a suspicious yellow card in his side's 6-0 win over Apoel Nicosia, with suggestions that the Spaniard deliberately got booked.
Youngster Jesus Vallejo is likely to fill in, with the back four remaining the same as it did against Athletic Bilbao at the weekend.
The three in midfield are also unlikely to change from the draw against Bilbao at the weekend, with Brazilian Casemiro being the more defensive-minded of the three.
Kroos and Modric controlled the game in the reverse fixture back in September, and if given the same time and space will do so come Wednesday night.
Just playing slightly behind a top two of Karim Benzema and Cristiano Ronaldo will be Spaniard Isco. The ex-Malaga man praised manager Zinedine Zidane recently for giving him the opportunity to play in his preferred position.
As for Ronaldo, it hasn't been the best season domestically for him, but after scoring twice at the Signal Iduna Park he will be hoping for a repeat come Wednesday.
