A running theme of Tottenham's season has been the different tactical systems used by Mauricio Pochettino.
Occasionally it's been nearly impossible to work out who is playing where until kick-off, a marked difference from last season when Pochettino stuck to a 4-2-3-1 formation, with the win at Watford the only exception.
"We are always finding different options, formations, animations during the game," the Spurs manager said on Tuesday. "Until now we have used three different formations, three different set-ups."
Now, it's four after Pochettino opted for a 3-4-2-1 formation in Wednesday's 3-0 win over Hull City.
