I'll introduce the disgusting peasants to something called form.
When a player consistantly plays and can build up, you can get in form, and when you stay fit and dont overplay, and work hard, you can keep a good form for most of the season.
Llorente, was out of the game for nearly an entire year. Then did SO much efford to get in there, at some point scoring nearly every game, he peaked hard. Now, he faces the inevitable drop of form, cause he doesnt have that continuity. In his case, there is also matchfitness and recovery, wich has to be taken in effect aswel considering this unique situation
When he has a good long summer without physical issues, he'll be in good shape starting next season, and will be much more consistant troughout it
