#4 Tottenham are paying the price for their frugality

Tottenham Hotspur threw away a three goal lead to Inter in the Champions League

Spurs have made tremendous gains in recent years, achieving relative success on a shoe string budget and making superstar players out of hitherto unknown quantities.

A lot of praise must go to Mauricio Mauricio Pochettino for his tactical nous in delivering results on a smaller budget than his PL rivals, however, there is a limit to where Tottenham can go with this model.

Football is big business now, and to achieve any from RM of sustained success, clubs must spend big. Atletico have realized this, same with Liverpool and Arsenal. However, Levy stubbornly refuses to adapt.

Spurs became the first Premier League club not to make a summer signing since the window officially started in 2003, as well the only club of the 32 UCL participants who didn't add to its squad.

The loss to Inter Milan made it three defeats on a row for Spurs, and they could well find themselves falling far behind their rivals, which would be a real shame for all they have achieved in recent years.
