Major League Soccer: D.C. United vs. Philadelphia Union (live, Sunday, 5 p.m. ET)
Reasons to watch: DC United have been one of Major League Soccer's best stories of the young season. Hoping to extend their 8-game unbeaten run, Ben Olsen's side find themselves perched atop the Eastern Conference and face a struggling Philadelphia side desperate for three points. Records aside, expect fireworks when these clubs collide.

International Friendly: USWNT vs. Mexico (live, FOX Sports 1, Sunday, 9 p.m. ET)
Reasons to watch: Fresh off of a 3-0 friendly win against the Republic of Ireland last Sunday, the USA women are looking to keep momentum going heading into the World Cup. Next on their Send-Off Series schedule is bitter rival Mexico. With just two games remaining until the USWNT makes moves to Canada, questions still loom. Star striker Alex Morgan has been ruled out against Mexico with a knee bruise. So whom will head coach Jill Ellis lean on to help fill the void? Sunday’s match could be telling.

Bundesliga: Stuttgart vs. Hamburg (live, Saturday, 9:30 a.m. ET)
Reasons to watch: This match is a straight six-pointer. Stuttgart are mired in the drop zone on 30 points, while Hamburg sit at 32, just one point clear of safety. With three clubs sitting between them with 31 points -- Freiberg, Hannover and Paderborn -- the stakes are massive. Since the Bundesliga’s creation in 1963, Hamburg are the only founding club to never be relegated from the top-flight. Beating the 2007 league champion could go a long way to preserving that honor.

Premier League: Manchester United vs. Arsenal (live, Sunday 11 a.m. ET)
Reasons to watch: This is always a big game but what’s at stake here is a matter of which team avoids having to play a UEFA Champions League qualifier to get into the lucrative group stages next season. United are two points behind Arsenal, who have a game in hand on their rivals. Avoid defeat and it’s likely that the Gunners will avoid that potential banana skin and a win at Old Trafford gives them a chance of finishing runners-up to champions Chelsea. United need just a draw to be mathematically certain of finishing in the top four.

Premier League: QPR vs. Newcastle (live, Saturday, 10 a.m. ET)
Reasons to watch: Last week’s 6-0 mauling at Manchester City condemned QPR to the Championship after just one season in the Premier League. Is it possible that Newcastle could join them in the second tier? That scenario remains a possibility. The Magpies are one place outside the relegation zone but crucially have two points on Hull City. Let’s not forget that Newcastle’s form is atrocious and if they do escape it will be because of their form in the first half of the season. Last week’s 1-1 draw with West Brom arrested an eight-match losing streak. It’s getting hot down there!

Premier League: Tottenham vs. Hull (live, Saturday, 10 a.m. ET)
Reasons to watch: All seemed well for Hull’s survival hopes when they beat Liverpool but the Tigers are now back in full crisis mode. Home defeats by Arsenal (expected) and Burnley (unexpected) have put Hull back in the relegation zone and with Manchester United looming in their final match of the season a win against Spurs is essential. Should Hull lose they can probably wave goodbye to the Premier League -- and Steve Bruce can think about getting another job.

Premier League: Liverpool vs. Crystal Palace (live, Saturday, 12:30 p.m. ET)
Reasons to watch: This game is about just one man -- Steven Gerrard. For those that probably never saw Kenny Dalglish in his prime, he is the greatest player to have ever worn a Liverpool shirt, and this weekend will be the last time his adoring fans will get the chance to see him play at Anfield ahead of his move to LA Galaxy. Expect emotion, expect tears and expect protracted applause to the tune of "You Will Never Walk Alone." The Reds still have a mathematical chance of finishing in the top four, but it’s about 1,000,000-1.

Premier League: Sunderland vs. Leicester (live, Saturday, 10 a.m. ET)
Reasons to watch: There is only one slot left to fill in the relegation zone and both of these teams are hovering dangerously just above that nasty trap door. Leicester are the form team in the Premier League having won six of their last seven games. A win for either side will confirm another season in the top flight but a draw wouldn’t be the worst result in the world. Both these teams will have a keen eye on what’s going on at White Hart Lane where Tottenham host Hull.

La Liga: Espanyol vs. Real Madrid (live, Sunday, 1 p.m. ET)
Reasons to watch: It’s kind of tough being a Real Madrid fan right now. There will be no Champions League final against arch-rival Barcelona, and in all likelihood, there will not be a 33rd La Liga title to celebrate either. Last week’s 2-2 draw with Valencia left Real Madrid four points behind Barcelona, which means even two wins from their final two matches will not be enough if Barcelona win one of their remaining matches. How much of a sulk must Cristiano Ronaldo be in right now?

La Liga: Atletico Madrid vs. Barcelona (live, Sunday, 1 p.m. ET)
Reasons to watch: Comfortably the biggest match of the weekend. Barcelona can win La Liga for the 23rd time in their history this weekend simply by matching or bettering Real Madrid’s result at Espanyol. Luis Enrique’s men could not be any more confident right now after reaching the Champions League final with an aggregate win against Bayern Munich midweek. Unfortunately for Barca, their opponents still have something to play for because they are four points ahead of Valencia with two rounds to go, and would like to avoid a Champions League qualifier. Even if they lose, they’ll still get another bite at the cherry at Granada next weekend.
