Pochettino will be saying something alone the lines
"We are going to New Maine Road to dominate City physically, in territory, in possession, and in goals. Yeah City are good but we are as good. Trust yourself. Trust the system. Trust your team mates. I expect to win"
Whether that is possible or will work, who knows? But that will be the plan.
What he wont say is "Sit back, hit the ball long and break at speed." That is not how Pochettino wants Spurs to play.
As for going full Cockney. God no. I aspired to be nothing more than a lily-livered liberal.
