Manchester United defender Phil Jones says he's comfortable in Louis van Gaal's back three system.
Jones is convinced he can flourish as part of a three-man defence under van Gaal.
"I personally enjoy the system," said the 22-year-old. "When everyone is working well together and knows what they should be doing on the pitch then it certainly works and is very difficult for teams to play against.
"I think the more we train and play, the more people understand their role on the pitch."
