With three games in Group E and F, Sunday's showdowns are Costa Rica vs Serbia, Germany vs Mexico, and Brazil vs Switzerland. Due to the multiple games being played, lineups are back to their normal constructions. Below we bring you seven players you should consider as World Cup DFS lineup picks for Matchday 4 (on June 17th, 2018).

Not all are top-tier options, as there is a range of DFS value picks, sleepers and high-risk players mixed in.

Consider all of these players for your DFS lineups; however, at the end of the day, it is always your decision. Good luck, RotoBallers.

WC DFS Forwards to Consider

Neymar - F, Brazil (DK - $12,100, FD - $12,500)

Despite the fact that he is coming into the game without full match fitness, Neymar is still one of the best players in the world. An enticing matchup against a weak Swiss side makes him a necessity in GPP formats due to his high ownership levels in contests. Neymar is a proven goalscorer and should work well with fellow forward Gabriel Jesus - as Brazil's talisman on the football pitch, Neymar is a must-own in your contests.

Joel Campbell - F, Costa Rica (DK - $6,400, FD - $7,500)

Joel Campbell is one of Costa Rica's best players despite the fact that he has failed to find a regular place in Arsenal's lineup since he signed with the team. At his price point, playing Campbell against an overrated Serbian backline could be a good value play at the position, especially in Tournament lineups. Campbell will likely play the full 90 minutes for Costa Rica and should be their main attacking outlet, making him a good option for fantasy owners who don't want to spend their salary cap on a top-priced option.

WC DFS Midfielders to Consider 

Marco Reus - M (FW on FD), Germany (DK - $7,300, FD - $9,000)

Especially on DraftKings, Marco Reus is a good bet to produce against a weak Mexico defense. Reus has always played well for the national team and should start on the left flank despite competition from Julian Draxler. Nevertheless, Reus has the ability to punish Mexico's defense and is a great value on DraftKings as a midfield option who is undervalued based on his current price. Therefore, you should put Reus in as many DK lineups as you can, regardless of format.

Valon Behrami - M, Switzerland (DK - $3,000, FD - $5,000)

If you are in need of a budget starter, Valon Behrami is expected to start for Switzerland as a center mid against Brazil. While his upside is capped, Behrami has the ability to contribute with an assist or goal against Brazil and is a bargain buy at just $3,000 on DraftKings. Although his FanDuel price is still a good value, he shouldn't be considered unless you are really strapped for cash. However, if you need a cheap midfielder, Behrami could be the way to go as the cheapest guaranteed starter on the slate.

WC DFS Defenders to Consider

Jonas Hector - D, Germany (DK - $4,900, FD - $5,000)

Despite rumblings that Michael Plattenhardt would start as the team's right back, it appears that Jonas Hector is going to start at fullback for tomorrow's game with Mexico. This makes him a terrific value on both DraftKings and FanDuel, as Hector is an attacking fullback who can contribute to both the team's offense and defense. In a game that Germany is expected to dominate, Hector is a good option out of the back who has the upside to provide for fantasy owners regardless of the contest type.

Bryan Oviedo - D, Costa Rica (DK - $4,400, FD - $4,500)

The ex-Premier League defender is still a starting fullback for Costa Rica; he could capitalize against a Serbian side with limited attacking creativity and an underwhelming backline. Therefore, Oviedo becomes a good option who has the ability to attack as well as defend from the fullback position. He screams value at the level below the elite options such as Kimmich or Marcelo. Expect a good game from Oviedo. He should be a solid bet in your lineups.

WC DFS Goalies to Consider

Keylor Navas - G, Costa Rica (DK - $4,300, FD - 4,500)

If you are trying to stack a Costa Rican defender with a goalkeeper against Serbia, Keylor Navas is an elite value at the position in a contest where most would go for Alisson (Brazil) or Manuel Neuer (Germany). Navas is a great stopper and is expected to get a clean sheet in a highly contested game and is on the team that is favored to win, making him a solid play in Tournament contests and a decent GPP consideration.

Good luck this weekend!
