David Moyes' Manchester United must overturn a 2-0 deficit to Olympiakos in the Champions League.
The first legs of the Champions League last-16 games did not fail to offer plenty of drama and excitement.
The majority of games remain wide open with plenty to play for, although it is likely that Paris Saint-Germain's 4-0 win at Bayer Leverkusen has all but guaranteed them a place in the quarter-finals.

Manchester United vs. Olympiakos
Games will not come much bigger than this for United manager David Moyes. His tenure at Old Trafford has been uneasy so far, with a third-round exit in the FA Cup, continued struggles in the Premier League and now a humiliating 2-0 defeat against one of the weakest sides left in the Champions League.
Despite their poor form in other competitions, United were rightly confident ahead of the game, and when Fulham signed Olympiakos' top scorer Kostas Mitroglou in January, Rio Ferdinand tweeted:
Fulham just signed our next CL opponents star man....good work Rene!! #TransferDeadlineDay— Rio Ferdinand (@rioferdy5) January 31, 2014
The magnitude of the first-leg defeat to Olympiakos can be summed up by many bookmakers installing Moyes as the Premier League manager most likely to get the sack next, as reported by Craig Hope at the Daily Mail.
However, United can still turn the game around, and in the likes of Wayne Rooney, Robin van Persie and Adnan Januzaj, they have the players to do so.
As reported by talkSPORT's Craig Bloomfield, no other club are as capable of winning from a losing position as United, and there are plenty of examples of them doing it on big European nights, including the Champions League final in 1999.
Bayern Munich vs. Arsenal
After making a positive start against Bayern Munich at the Emirates, Arsenal took their eye off the ball and slipped to a 2-0 defeat.
Mesut Ozil's penalty miss and Wojciech Szczesny's red card swung the game in Bayern's favour, and the European champions, 19 points clear and unbeaten at the top of the Bundesliga, are not ones to miss an opportunity.
Despite their confidence being knocked by defeat, Arsenal showed enough in the first half to give them a fighting chance if they can score early. The return of top-scorer Olivier Giroud, who, as reported by ESPN FC's Kevin Palmer, was mysteriously dropped for the first leg, will boost the Gunners, and the 4-1 Premier League win against Sunderland on Saturday showed that they are still fighting.
Barcelona vs. Manchester City
A poor first-leg display from City allowed Barcelona to take a comfortable two-goal advantage back to the Nou Camp.
Not much is likely to change in the second leg, Barca have only lost at home once this season, per ESPN FC, but the Catalan side are not as strong as they once were and are vulnerable in defence.
Injury-prone veteran Carles Puyol is rumoured to be considering retirement, as reported by Sky Sports, but Barcelona have not found a new defensive leader to replace him.
TalkSPORT's Lee Roden explained last summer that Barca must replace Puyol to ensure their candidacy as a side capable of winning the Champions League:
Barcelona's board need to make a statement by solving the clear problem area in their side: replacing Carles Puyol at the heart of defence. In order to do so, there are two options: promote from within, or spend money. Neither is particularly straightforward...
The return of Sergio Aguero, as reported in the Daily Mail by Joe Strange, will help City unsettle Barca's defence, but it won't be enough to help them stay in the Champions League.
