Hi, new poster. With the squad available I'd say Pellegrini, Loptegui, Blanc (might be out of a job soon), Lucien Favre, Roger Schmidt,De Boer, Karanka and Howe.
In that order. Pellegrini, Favre, Scmidt and Howe play 442, which is now back as a stable tactic, while the others favour 433 morphing to 4231.
Schmidt in particular would be a BOLD choice, but one worth taking if you watch his Leverkusen side.
