10. Jón Daði Böðvarsson
Jón Daði Böðvarsson is the first name on the list at number ten, with the Icelandic international first signing for the club back in 2019.
He had previously played for Wolves and Reading, and caught the eye with some strong performances for both of them, but struggled for consistent goals.
It’s been a similar story with Millwall for the striker, as he’s scored just once in 40 appearances in all competitions for the Lions this term.
At the age of 28 though, he’ll still feel as though he’s got something to offer Millwall heading into the 2021/22 season.
