4-4-2 Diamond/4-1-2-1-2 (Obb)
Similar to the 4-3-3, the 4-4-2 diamond formation also allows Thailand to get the best out of the 3 J League-based players. The biggest strength of the diamond formation is that it helps team controlled possession thanks to the 4 central midfielders which tend to outnumber the opposition 3-man midfield. In this formation, Chanathip Songkrasin can operate in his preferred number 10 position with 2 strikers in front of him. And like the 4-3-3, the diamond gives Thitipan the freedom to bomb forward unlike the 4-2-3-1 where the Trinita midfielder would have to start his runs from the deeper double-pivot position.
Park Hang-seo’s Vietnam often adopts a 4-2-3-1 formation and is very effective at playing on the front foot, pressing aggressively high up the pitch. However, if that doesn’t work, the Golden Dragons are also happy to drop to a low-block, invite the opposition to bring the ball forward, then hit back on the counter with the pace and direct plays of talents such as Nguyen Cuong Phong or Nguyen Quang Hai. See for examples, both of Vietnam’s AFF Suzuki Cup final against Malaysia or the second half of the Kings Cup in Buriram.
Still, the diamond formation is not without its weakness. Jamming 4 players centrally meant there is no width in attack or defense. In this system, the more attacking-minded Tristan Do and Narubadin Weerawatnodom would be the better option at right-back instead of Nitipong Selanon.
Upfront, the 2 strikers is also responsible for providing the width and is expected to drift wide in certain situation. In this case, it could turn out to be positive for Thailand considering the number of wingers or attacking midfielder in the team.
Supachok Sarachat plays this wide-left forward role so well for Buriram United and should get a chance if Nishino uses this formation. Even Bordin Phala, Ekanit Panya or Chanathip could play there.
