There was a surprise guest at stadium:mk when MK Dons beat Manchester United 4-0 in the second round of the Capital One Cup.
Indeed, Spurs boss Mauricio Pochettino graced the stands in Milton Keynes for front-row seats to a spectacle all non-United supporters would have loved to see first hand. And the League One side have since won their third-round tie in the competition, beating Bradford City 2-0.
But why was he there?
Alli has scored six in 11 and one of League One's hottest properties could be available for £10 million in January.
It is Liverpool, though, that have been most heavily linked with the midfielder, having reportedly had a £3.5m bid rejected for him in the summer.
Spurs could rival their interest now, with Pochettino being impressed with what he saw during his scouting trip to stadium:mk. German champions Bayern Munich, however, are also said to be interested.
Back in the Premier League, Tottenham travel across north London to face Arsenal at the Emirates Stadium this Saturday evening, although a tough Capital One Cup tie against Championship leaders Nottingham Forest awaits them first, with Stuart Pearce's men visiting White Hart Lane tonight.
