Wednesday night saw Tottenham dumped out of Europe at a disappointingly early stage once more. After Son Heung-min's scuffed shot gave the North-Londoners the lead in the first-half, Juventus rallied after half-time via goals from Argentines Gonzalo Higuain and Paulo Dybala.

Calling upon all of their traditional Italian defensive mettle, Juventus held on in the face of Tottenham pressure, to leave London with a gutsy 2-1 win and a place in the Champions League's quarter-finals.

Can Spurs hold onto their key men?

Despite praise from fans and the media alike for their swashbuckling style of play, yet another European failure condemns Pochettino's men to an underwhelming season.

They are impossibly adrift of runaway Premier League leaders Manchester City. With only the FA Cup and a place in the top-four to fight for, Tottenham fans will be wondering if this summer's transfer window will see an exodus of the club's prized possessions, chief among them (almost) unstoppable goalscorer Harry Kane.

Whilst the infectious team spirit and fluid style instilled within the players by Mauricio Pochettino are reasons to remain at the club, Tottenham's best players must ask themselves a question: do I have to move to win trophies? It seems increasingly likely that the answer to that question may be "yes." How many more seasons can Kane and co give to the club before their careers stagnate and vast potential turns into waste?

The drastic decline of bitter North-London rivals Arsenal, should serve as a stark warning.

The ecstasy of gold

Any potential exodus from White Hart Lane may stem from a different source than a player's desire to advance his own career. In light of reports that the building of Tottenham's new stadium, due for completion early next season, may cost upwards of a billion pounds, Chairman Daniel Levy and the Spurs board may have no choice but to sell off their most valuable playing assets in order to mitigate the club's financial woes.

Englishmen Harry Kane and Dele Alli, in particular, will command exorbitant transfer fees in today's inflated market and, with no shortage of suitors, the siren's call of cash may prove too tempting for Levy to resist. With superpowers like the Manchester clubs and Paris Saint-Germain inevitably looking to splash the cash this summer, the time might well be right for Spurs to nudge some of their biggest names out of the door.
