Spurs are in the Champions League this season, and doing well.
They got there by achieving a top-four league position last season.
The income from a decent run in that tournament can be well of £50m and goes a long way to keeping a team strong enough to stay in the top four.
That, of course, is exactly what Chelsea, Manchester United, Liverpool and Arsenal have done for years.
Spurs dislodged Liverpool last year and that sent the Merseyside outfit on a downward spiral and it is highly unlikely that Liverpool will be in the chase for a top-four place this season.
The knock on effect is that the very best players want Champions League football and no matter how much money is offered they wont sign—ask Manchester City about that.
But as it stands today, Spurs are only a rank outsider to make it back into the Champions League (winning the tournament would get them back in but that is a big, big ask).
And that will not do as the owners of Spurs have planned around being there, with the big boys.
The new stadium plans need Champions League money to make them viable.
The squad development needs that Champions League lustre to make it attractive.
So panic has hit the London club and on the last day of the January transfer window they have made bids totalling over £90m in a money-is-almost-no-object attempt to buy a decent goalscorer.
But it seems as if Spurs' dreams are fading now and if they miss out this year the opportunity will be very hard to grab again.
So an all or nothing push on deadline day is perhaps the last roll of the Champions League dice for Spurs.
