Adams has used at least three different formations in pre-season: the diamond (4-1-2-1-2),a 4-2-3-1 and a 4-4-2. In the first two, Wes has a big role to play, but the latter doesn't suit him. Judging from pre-season, the first two look like being the most common, IMO. Although the 4-2-3-1 looks like a sole striker formation, Adams uses it to play Redmond and Grabban on either side of Wes and behind Lafferty or Hooper, which makes it a very attacking formation with pace and penetration. The Diamond is also attacking, but allows Wes, Surman, Howson, Fer and presumably O'Neil to probe defences with intelligent through balls to the two strikers.
