5. Luis Suarez
Before we lament Luis Suarez's past misdemeanours its well worth noting that the Liverpool striker's attitude has been nothing exemplary since returning from his latest suspension, with 22 goals in 17 Premier League matches to show as proof.
The face remains though that Suarez has let down his Liverpool team-mates consistently with past actions, including a combined 18 matches on the sidelines for successive bans attributing to biting Branislav Ivanovic and racially abusing Patrice Evra.
Suarez is desperate to guide Liverpool to Champions League qualification but will always be a question mark in terms of long-term commitment and attitude because of previous behaviour.
