Manchester United vs. Paris Saint-Germain
When this tie was initially drawn, few gave the Red Devils a chance of getting past the French champions over two legs. Now, though, the game is an extremely tough one to call.
Primarily, that is due to the fact that since caretaker manager Ole Gunnar Solskjaer took over at Old Trafford, his team have been rejuvenated. There's a fizz back in their football that was scarce for so long under Jose Mourinho; the Norwegian is getting the best from key players again, too.
Arguably, the most significant turnaround in form has been seen in Paul Pogba, who was on the scoresheet twice in the 3-0 win over Fulham on Saturday.
The France international has been banging in the goals as of late:
PSG appear vulnerable, too, and manager Thomas Tuchel will be taking a patched-up side to Old Trafford.
While Marco Verratti's return was a big boost on Saturday against Bordeaux, Edinson Cavani was substituted at half-time with an injury. It means he is set to miss the clash, with Neymar also absent.
United, by comparison, have had ideal preparation:
With that in mind, United will edge this encounter at what should be a raucous Old Trafford. PSG's midfield issues will allow the hosts to take a foothold in the game, and the French outfit will have a deficit to make up in Paris on March 6.
Prediction: Manchester United 2-1 Paris Saint-Germain
Ajax vs. Real Madrid
Following a calamitous start to 2018-19, Real Madrid are settling into an ominous groove just in time for the knockout stages of the Champions League.
After a draw at Barcelona in the Copa del Rey last week, they went to rivals Atletico Madrid on Saturday and earned a brilliant 3-1 win. The authority and quality that has been associated with their three successive European Cup successes appears to be returning.
Spanish football journalist David Cartlidge commented on how well Los Blancos performed at the Wanda Metropolitano:
Still, this is the third tough away game in a week for Madrid, and Ajax are not an opponent to be taken lightly after an impressive group-stage performance.
In Matthijs de Ligt, Hakim Ziyech and Frenkie de Jong, who will join Barcelona in the summer, the Dutch side have a crop of high-class young players.
Even so, you sense the experience and confidence Madrid have going into the game in Amsterdam will see them earn a positive result on the night, even if Ajax have the potential to be testing opposition.
Prediction: Ajax 1-2 Real Madrid
