However, this experiment didn't really work out and then Southampton have mostly played a conventional, if rather narrow, 4-3-3.
The crowd became a little nervous and it said everything about how the second-half had gone from Tottenham's point of view that, in the 75th minute, Pochettino took off Son and brought on an extra midfielder in Harry Winks. But the good thing he is very positive.
On James Ward-Prowse and Nathan Redmond being part of the England squad: "I told them I had a problem with their attitude in the training session, and to ask their opinion".
"It's important he understands he has all the quality to become a very good striker with his feet and his quality". Which was the 79 head to head among Tottenham and Southampton. Kieran Trippier and Son Heung-Min have both been a success but neither gets in the first XI when everyone is fit.
"He's very clever in the box - he looks like a striker, because he's more than clever".
Spurs thought they had found the key to Southampton's success when they poached Paul Mitchell and his "black box" to head up recruitment in November 2014 but they were sold a dud. "It was good for Toby and Victor because they felt at home from day one and showed the quality to play football at Tottenham", Pochettino said on Friday.

They could even have added a third goal before the end of the game when Vincent Janssen, on as a second-half substitute, bulldosed his way through the Saints defence but saw his powerful shot saved by Forster. But Tottenham lost at home last time with Southampton.
The 22-year-old scored against Millwall last weekend, which was Janssen's first from open play since joining in a £17.5m deal from AZ Alkmaar eight months ago.
Spurs are the only side in the English top-flight yet to suffer a defeat on home soil this season.
He has however struggled to adapt to life since arriving at the North London club, with four out of the five goals he has netted in all competitions this season coming from the penalty spot.
Spurs have only once had a better overall record at this stage of a top-flight campaign - in their title-winning 1960-61 season.
This would constitute a terrific achievement and these three points maintained a seven point lead over Manchester United in fifth and a nine point advantage of Arsenal in 6th.
