#1 Diego Rico (Bournemouth)
Spanish football fans know all about Diego Rico, but his first season in England was a major disappointment in 2019-20. The former Leganes and Zaragoza man failed to cement a place in the team and managed just 12 games in the league. The team ended up playing exactly one million euros for each of his Premier League appearances.
Rico is one of Bournemouth's biggest ever signings, and manager Eddie Howe likely still has high hopes for him. The 26-year-old left-back is a technically gifted player, who's also on set-piece duties when he plays, so he has a very important role to play.
He's also nicely set up for success at Bournemouth after first-choice left-back Charlie Daniels spent a chunk of the preseason nursing an injury.
Full-backs have a big role in Howe's gameplan, which resulted in four goals and three assists for Daniels in 2016-17. Rico could easily match these numbers in 2019-20, or even better them, if he makes the left-back position his own.
