Rennes midfielder Nemanja Matic admits Jadon Sancho had poor timekeeping when he was still with Manchester United.
Matic says he couldn't believe the difference between Chelsea and United in terms of professionalism.
On YU Planet, he revealed: "At Chelsea, players acted professionally, they were punctual and were never late for training but at United it happened almost every day."
The Serbian continued to name the two players who angered their teammates most at United.
"Among the players who would always be late were Paul Pogba and Jadon Sancho and couple of other players," he continued.
"The rest of us who were always on time were angry so we decided to form a kind of an internal disciplinary committee with me serving as its president.
"I put a sheet of paper up on the wall where I documented the names of individuals arriving late. During one particular season we collected around £75,000 in fines."
