4. Roberto Soldado
Tottenham Hotspur striker Roberto Soldado arrived at White Hart Lane last summer for a then club-record £26.5m fee, with a reputation as the continent's most clinical finishers earned during a prolific spell at Valencia.
Unfortunately for Spurs fans the only place Soldado has consistently scored from this season is the penalty spot, registering a paltry six goals in 26 Premier League games.
The Spanish international looks a player short on confidence but also lacks the work-rate, pace or strength to play up front on his own, which gives Spurs a big problem when Emmanuel Adebayor is fit and firing.
