Chelsea loan army: Keep, loan or sell? Danny Drinkwater (Part 20)

In Part 19 of this series, I broke down Ross Barkley's career at Chelsea and discussed what his future in football looks like. For those who haven't read the introductory piece to this series, a different player will be the subject of a new article every day. I began with goalkeepers and am currently in the process of working my way up the pitch, with each position group being sorted in order by the way in which they appear on the club's website.
