3-4-2-1
Roberto Martinez has used variations of this formation in the Premier League with Wigan Athletic and Everton in recent years.
A 3-4-2-1 could really suit Spurs. After all, Pochettino likes his central defenders to split and play wide, so converting to a back three would only be a minor change in that regard.
Mousa Dembele and Etienne Capoue could provide extra defensive protection, with hard-workers Lennon and Danny Rose getting up and down the flanks.
In Eriksen, Paulinho and Adebayor, Spurs would have three genuine goal threats in central positions.
