LEC 2025 Summer Week 4 tips & best odds – Tuesday, August 26

The final week of the League of Legends EMEA Championship 2025 Summer group stage concludes with a pair of contrasting matchup on Tuesday, August 26.

Team Vitality and KOI will battle it out for second place in Group A, followed by a clash between GIANTX and Natus Vincere — the bottom two sides in the division.

The two fixtures offer some strong LoL betting opportunities heading into the LEC Summer playoffs, which kick off next month.

Team Vitality have managed two wins this split, including an upset victory against Karmine Corp last Monday. Their run also includes a head-scratching loss to GIANTX; however, with back-to-back wins in their pockets, Vitality are on a confidence boost ahead of their clash with the defending LEC champions.

KOI have been a bit shaky over the last three weeks. They had a few issues against GIANTX, lost to Karmine Corp in three maps, and then needed a comeback to beat Natus Vincere.

Even though KOI are a good team, they’ve not looked as sharp as they were at the end of last split. Still, the best LoL betting sites have them priced as firm favorites to take down Team Vitality, who have been a bit up-and-down as well.

Both squads have had iffy moments in LEC Summer, so it is easy to imagine a close game.

NATUS VINCERE vs GIANTX

Best Odds: NAVI +350 at BetOnline | GX -625 at BetOnline

GIANTX have managed just one win this split; however, their map record is solid at 4-4, having taken maps off both Karmine Corp and KOI. A lot of it has to do with their strong early game, averaging a +772 gold difference at 15 minutes and the league’s second-highest first blood rate (87.5%).

However, while GIANTX have shown good things, it is hard to justify their -625 tag for this game.

Natus Vincere have not won a single match or map this split, but they had their moments against KOI last week and even a had chance to take a map off Team Vitality. Moreover, the two teams are not playing for anything; NAVI are out of the playoff race, while GIANTX are guaranteed a spot in the lower bracket.

With nothing on the line, NAVI to take a map at even money is an appealing bet.
