Sunderland manager Paolo Di Canio has claimed that he will fine any players who return to pre-season training overweight.
The Italian is preparing for his first full campaign in charge of the Black Cats after arriving at the Stadium of Light in March.
"Obviously the players have a programme to follow so that they are ready when pre-season begins," The Sun quotes Di Canio as saying.
"Everyone who comes back with more than 2kg over what their weight should be, we're going to fine them."
Sunderland finished last season in 17th place in the Premier League table.
