What both Spurs and now Liverpool can stand accused of is failing to think big. They tried to be prudent - and fair enough. But they can be both prudent and also take that one big plunge as well. And we are not talking about Mario Balotelli. No-one would blame a club further down the Premier League, with lower ambitions, and fewer resources – West Bromwich Albion, Stoke City, Sunderland – of selling a superstar if they possessed one and using it to bring in several players to strengthen their squad.
