The second week of ESL Pro League Season 4 features a matchup between two teams whose recent roster changes will heavily dictate their results going forward: mousesports acquired Tomáš "oskar" Šťastný on Monday while Fnatic swapped out three players and their coach last week.

oskar comes into mouz following a stint on HellRaisers that saw him put up great individual numbers but fail to translate those impressive performances into results. In a sense, he's a kindred spirit to Nikola "NiKo" Kovač who has had a very similar career on mouz. With both players now on the same team, it stands to reason that when one falters, the other should be able to pick up the slack.

Fnatic's changes were more comprehensive and harder to get a read on. They traded away in-game leader Robin "flusha" Rönnquist and brought in a new coach in Jumpy. It's still not clear how those changes will affect the team from a strategic standpoint.

Fnatic have also made a somewhat odd move by bringing John "wenton" Eriksson back to their primary roster. He filled in for them when Olof "olofmeister" Gustafsson was sidelined by an injury and now he has big shoes to fill once again — arguably bigger shoes now as the team's in-game leader.

Both teams share a 1.04 average over the past three months, which is quite the feat for Fnatic considering wenton's abysmal 0.85 rating. With that said, his rating could hide his true impact as the team's support player, especially as the new IGL.

On the other side, mouz look top heavy with both NiKo and oskar posting numbers higher than Fnatic's best players — and even though wenton's numbers are particularly bad, their support line still averages out better than mouz's.

According to a fragbite interview with Fnatic's former coach vuggo, olofmeister will be the team's main AWPer, however, he noted that either Dennis "dennis" Edman or Simon "twist" Eliasson could also serve as the team's AWPer depending on the day.

Map matchup

Fnatic (W:6) Map mouz (W:1) 19 Dust 2 17 19 Cobble 17 16 Train 5 16 Cache 13 17 Dust 2 19 16 Cache 4 19 Dust 2 17

(Note: Head-to-head matches from 2016)

The first game going to Dust 2 and the second one going to Cache comes as no surprise given the map history between these two teams. There's an odd map on Cobble and Train, but their matchups have been predominantly played on Dust 2 or Cache.

Fnatic have a big upper hand in the head-to-heads, winning six out of the seven maps, but it's also worth noting that they've had to fight tooth and nail for their victories, with four of the seven maps going to overtime.

Fnatic (W/L - W%) Map mouz (W/L - W%) 6/1 - 85.7% Cache 1/3 - 25% 5/2 - 71.4% Dust 2 6/4 - 60% 2/3 - 40% Mirage 4/2 - 66.7% N/A Nuke N/A 3/0 - 100% Train 5/3 - 62.5% 8/2 - 80% Cobble 1/6 - 14.3% 0/1 - 0% Overpass 1/1 - 50%

(Note: Stats aggregated from HLTV.org on Aug. 22, filtered by "Past 3 months.")

Given the head-to-head and the team's recent overall map performances, the second game on Cache should be in the bag for Fnatic, unless the changes on both teams drastically shift their respective performance on that map. The deciding factor for this series will be on Dust 2, as both teams have similar records on the map against other teams of similar strength, as well as each other.

Tournament matchup

Fnatic Tournament mouz 2nd ELEAGUE Season 1 3-4th 3-4th ESL One Cologne 2016 9-12th 3-4th ECS Season 1 DNQ 3-4th ESL Pro League Season 3 DNQ

(Note: Only looking at tournaments both teams were participating in, since the end of MLG Major Championship: Columbus.)

Though Fnatic aren't the same team as the one that won six LAN tournaments in a row, they at least maintained consistent Top 4 finishes. mouz continued to have inconsistent performances in 2016, but their most recent finish at ELEAGUE was the team's best to date, and they are looking to continue that upward projection with oskar.

It's a new beginning for both teams, but who will make the first big impact with their new lineup?
