The Champions League round of 16 concludes this week, with four quarter-final places still up for grabs.
After comprehensive displays away from home, Real Madrid and Borussia Dortmund welcome Schalke and Zenit St Petersburg, respectively, knowing they must surely advance to the last eight.
The Galacticos beat their German opposition 6-1 and will progress barring a miracle. Dortmund, meanwhile, won 4-2 in Russia to leave Zenit with a near-impossible task in the second leg.
England's last existing representatives, Manchester United and Chelsea, face Olympiakos of Greece and Galatasaray of Turkey.
The west London club managed a draw from their first encounter with Gala. However, United were shocked against their less-fancied opponents, losing 2-0.
Here is a list of fixtures, predictions and all the information needed to watch the action:

Real Madrid v Schalke
Football matches at the highest level are rarely a procession.
However, with Madrid doing all of the hard work in the first match it would be logical to presume that we will see something of an understrength team fielded to finish the job against Schalke.
Madrid were the competition's leading scorers during the group stages scoring 20 times, per UEFA.com.
They are in the round of 16 for the 11th straight time, and the quarter-finals awaits them unless we see one of the biggest shocks in Champions League history.
The Spanish giants have won seven and drawn twice to German opposition at home, since their defeat to Bayern Munich in 2001 in the Santiago Bernabeu.
With Schalke having only pride to play for, and with Madrid convinced the job is done, a surprise could be on the cards on Tuesday.
However, with the depth of talent at Madrid's disposal, and with both clubs pursuing domestic commitments, the expected comfortable victory for the Galacticos should be forthcoming:
Prediction: 3-0 win for Real Madrid
Chelsea v Galatasaray
Jose Mourinho will have been satisfied with his team's score draw in Turkey, taking away a vital away goal with them to defend, back at Stamford Bridge.
With the focus being on Blues legend Didier Drogba's return to west London, the Portuguese manager will use the attention to deflect the pressure from his team
ITV reports that Mourinho said of Drogba's return: "Bring the King back to Stamford Bridge. Didier deserves to come here and to feel the passion and the respect. I would love that."
Drogba in turn responded, via UEFA.com: "I am quite apprehensive about it. It is a very special moment because I do not know what my reaction will be."
If the nerves and the emotion get to Drogba, it should be a comfortable night for the Blues.
With the electric form of Eden Hazard, Gala should have no resistance to the little Belgian's brilliance, and will see Chelsea progress to the last eight.
Prediction 3-1 win for Chelsea
Borussia Dortmund v Zenit St Petersburg
Jurgen Klopp's men made short work of their opponents, Zenit, in the first leg but will be disappointed to have conceded twice, leaving the Russians with the slimmest of hopes.
Dortmund's four away goals should be more than enough to see them through should Zenit somehow manage to tie the scores on aggregate.
Zenit's form in the Champions League has been poor of late. They have only won once in their previous six matches in Europe, per UEFA.com. That was a 1-0 victory in Portugal against Porto last October.
In stark contrast, Dortmund have won four of their last six Champions League games, losing in the group stages to both Arsenal and Napoli.
As with Madrid, we may see Klopp opt to field a weakened team to see his team home. It should be a comfortable night for last season's finalists.
Prediction: 2-0 win for Borussia Dortmund
Manchester United v Olympiakos
Life for David Moyes really does not get any easier.
This season has been a disaster for the reigning Premier League champions, and that was reflected in the first leg of this match. United lost 2-0 and gave one of their worst performances of the season.
The Red Devils now need three goals in reply and hope that their plucky Greek opponents do not steal an away goal.
Olympiakos have lost on all of their previous 11 occasions playing in England, per UEFA.com, and a win looks unlikely once again despite United's form.
However, as United leak goals for fun at the back, it looks entirely possible that the Greeks will grab the away goal that they need.
The encounter should be a close one if the Reds' attackers turn up in force, but ultimately it could be a heartbreaking night once again for Moyes and Co.
Prediction: 3-1 win for Manchester United
