Sunderland boss Paolo di Canio plans to fine players who put on weight.
The Italian taskmaster has warned his Sunderland players they must report back to pre-season training in virtually the same shape as they were when they jetted off on their holidays last month.
Di Canio said: "Obviously the players have a programme to follow so that they are ready when pre-season begins.
"When we start, we will start not that heavy, but there will still be a great deal to do and they have to be ready.
"It's normal in the Premier League, that players get punishment for breaking rules set down by the club.
"Everyone who comes back with more than 2kg over what their weight should be, we're going to fine them.
"We test them before they go so everyone knows how they finished the season."
