I misread the article, Bolton have 6 senior contracted players.

https://www.reddit.com/r/soccer/comm...ve_six_senior/

The six players for those who might not recognise the names:

GKs: Ben Alnwick, Remi Matthews
Midfield: Jason Lowe, Luke Murphy, Erhun Oztumer
Attack: Josh Magennis

The rest of the players listed on the website are youth team prospects who have maybe a dozen first team appearances between them.
