3. Erik Lamela | Tottenham
Tottenham smashed their transfer record in the summer to sign Erik Lamela, who cost a cool £30m, from AS Roma.
However, partly due to his struggles adapting to life in England and partly due to the impressive performances of Andros Townsend, Lamela has featured in just five Premier League matches this season - and made his first start during the humiliating recent 6-0 defeat at Manchester City.
Andre Villas-Boas needs the Argentine winger, who possesses plenty of talent, to start producing the goods - and quickly.
