The history of manager books in mid-job at such times doesn't bode well, and can be tantamount to giving away trade secrets - their secret formula - but the Spurs boss doesn't mind. The wonder is now what he'll come up with against Liverpool, and should invert the recent history of this fixture in that it will make it more hard for Jurgen Klopp to plan for.
Poch has used a variety of formations this season, including 3-4-3, 3-4-2-1, 4-4-1-1 and his old favourite 4-2-3-1.
Pochettino, 45, confessed: "It was wonderful". It was awesome because some people close to us said: 'When we saw the starting XI [against Real Madrid] we thought what the eff? "What is going on in his mind?'"
"Ten minutes after the end of the game, they said 'you are a genius!' I said 'ok thank you!" It's about trying to find the right time to provide him the place and the opportunity to play.
"They are young and make mistakes but the most important thing is that they learn from that".
And that improvement allows him to switch formations as his players believe in his methods.
"Sometimes it works, sometimes it doesn't, but I feel the same after the game if I win or lose, about my decision, because I can not regret my decisions".
"If I win or lose, I can not regret my decisions".
Substitute Alex Oxlade-Chamberlain, with his first Liverpool goal, and Trent Alexander-Arnold completed the rout in the closing stages as the visitors registered their biggest win under manager Juergen Klopp.
"This not only happens in Tottenham, it happens around the world". But he has not surprised me. We must wait for when he sees the specialist and then we'll see what happens.
And Pochettino explained: "Last season it was hard to cope with competitions - the Champions League and the Premier league". "Different circumstances, different teams, different clubs... but it's not a five-year record or 10-year record". Today, we have available the same number of players and similar injuries, but because the team has moved on, improved, learned, we're competing much better. He is part of my plans.
Rose caused controversy during the summer when he claimed that Spurs players are underpaid and added that he would be willing to leave the club if he received an offer form a team that can regularly challenge for trophies.
