Tottenham’s move for Janssen has been held up by ‘Moneyball’ brainchild Billy Beane, who advised AZ to hold out for £17m and reject the London club’s first two bids.

But Spurs have not been put off and Pochettino wants the Janssen deal wrapped up before moving on to his next target, which will be an attacking midfielder.

As ever, Pochettino’s team of scouts and analysts have drawn up an extensive list of potential targets in that position – one of whom is believed to be Newcastle United’s Wijnaldum.
