If we’ve learned anything leading up to Week 5 in the NFL, it’s that there are some big quarterback problems for the Minnesota Vikings and Washington Redskins.

Kirk Cousins isn’t getting much love from his Vikings wide receivers, with Stefon Diggs set to play against the Giants after trade rumors dominated the week, while Washington coach Jay Gruden won’t give the reins over to first-round draft pick Dwayne Haskins, but rather journeyman Colt McCoy for a matchup wit the Patriots.

Meanwhile, Chicago Bears MVP candidate Khalil Mack will get a chance to show the Oakland Raiders that he isn’t over their breakup and the Green Bay Packers and Dallas Cowboys put their rivalry in the forefront in a primetime game.

Here’s what we’ll be watching for in Week 5:

Chicago Bears vs. Oakland Raiders (1 p.m. ET, FOX)

Cheerio. London has not been treated to many good games since the NFL started bringing games there every fall, but this one has some potential. If nothing else, it will be Mack’s first chance to suit up against his former team since Jon Gruden traded him away. That alone should be worth the price of admission, and the Bears’ monster pass rusher is already in midseason form with 4.5 sacks and four forced fumbles in four games.

The Raiders have been up-and-down to start the year but are coming off an upset win over the Colts and will try to keep their momentum going. They get a chance to face a Bears team quarterbacked by Chase Daniel, who is starting in place of the injured Mitchell Trubisky. Gruden may need some tricks to get past the Bears defense.

Tampa Bay Buccaneers at New Orleans Saints (1 p.m. ET, FOX)

Which version of the Buccaneers shows up? The one that choked up a big lead to the Giants in Week 3 or the one that outlasted the Rams in a 55-40 shootout win in Week 4? Jameis Winston remains an enigma, but with two stud receivers in Mike Evans and Chris Godwin, it’s an offense that’s capable of damage.

The Saints offense, meanwhile, has been inconsistent since Teddy Bridgewater took over at quarterback for the injured Drew Brees, but with weapons like Alvin Kamara and Michael Thomas, they remain dangerous of popping off at any time. They could use some help from their defense like they did a week ago to beat the Cowboys.

Green Bay Packers at Dallas Cowboys (4:25 p.m. ET, FOX)

The two franchises have plenty of history, but this Sunday’s matchup should be a good one, too. The Packers might be missing star receiver Davante Adams because of a toe injury, but they still have Aaron Rodgers, who can hurl it a time or two. They enter with some extra rest, too, after falling in crushing fashion to the Eagles last Thursday.

The Cowboys are also coming off their first loss of the season against the Saints, who shut down Dallas’ high-powered offense. Dak Prescott and Ezekiel Elliott will look to get back on track against another tough opponent and try to prove their fast start wasn’t just the product of facing the Giants, Redskins and Dolphins.
