5. Roberto Firmino – Liverpool
Another of Brendan Rodgers’ summer signings with a sizeable transfer fee to live up to. The Brazil international looks some way off the pace of the Premier League, and Liverpool fans could grow impatient if he doesn’t start to deliver quickly. He may well have been the most creative player in the Bundesliga over the past two seasons, but England is whole new ball game, and the pressure to perform will be high on the 23-year-old.
