There was a time when Mauricio Pochettino was criticised for not having a Plan B; for being too tactically inflexible. Now it has become unclear what Plan A is -- if anything there has been too much tinkering.
Spurs started the season using his favoured 4-2-3-1 formation but after a spell with a 4-1-4-1 system and an unsuccessful trial of a 4-4-2 midfield diamond, he moved to 3-4-2-1.
The catalyst was the limp 1-0 defeat at Manchester United in December, when Kyle Walker and Danny Rose were neutralised. Pochettino opted to deploy the duo as wing-backs in the following game against Hull and the result was a 3-0 win.
